Dual-functions of the carbon-confined oxygen on the capacitance and cycle stability enhancements of Zn-ion capacitors Yi Zhang, Zhimin Zou, Qi Liu, Yu Qiao, Chunhai Jiang J. Mater. Sci. Technol.    2025, 221: 278-288.   DOI: 10.1016/j.jmst.2024.10.003 Abstract （269）      PDF       Knowledge map    Zinc-ion capacitors (ZICs) are promising energy storage devices due to their balance between the energy and power densities inherited from Zn-ion batteries and supercapacitors, respectively. However, the low specific capacitance of carbon cathode materials and the dendrite growth on Zn anode have set fatal drawbacks to their energy density and cycle stability. Herein, we demonstrate that, in 1 M Zn(CF3SO3)2/DMF (N, N-dimethylformamide) electrolyte, confining oxygen in carbon cathode materials via high-energy ball milling can synergistically introduce additional pseudocapacitance on the cathode side while suppressing the dendrite growth on Zn anode side, which jointly lead to high energy density (94 Wh kg-1 at 448 W kg-1) and long cycle stability of ZICs. The hydroxyl group in carbon cathode can be transformed to C-O-Zn together with the release of protons during the initial discharge, which in turn stimulates the defluorination of CF3SO3- anions and formation of ZnF2 on both cathode and anode. The ZnF2 formed on the surface of the Zn anode suppresses the dendrite growth by regulating the Zn2+ deposition/stripping in a reticular structure, resulting in the excellent cycle stability. This work provides a facile strategy to rationally design and construct high energy and stable ZICs through engineering the oxygen-bearing functional groups in carbon cathode materials.

Multi-stimulus responsive actuator with weldable and robust MXene-CNTs hybrid films Xueyuan Qiu, Xiao Han, Baorui Dong, Meng Zong, Runtong Zhou, Teng Zhang, Pan Wang, Chang Guo, Hejun Li, Jianhua Hao J. Mater. Sci. Technol.    2025, 222: 164-173.   DOI: 10.1016/j.jmst.2024.08.062 Abstract （175）      PDF       Knowledge map    Stimulus-responsive actuators are novel functional devices capable of sensing external stimuli and exhibiting specific deformation responses. MXene, owing to its unique 2D structure and efficient energy conversion efficiency, has bridged the gap in traditional devices and shown great potential for multiple stimulus-responsive actuators. However, the drawbacks of pure MXene films, including susceptibility to oxidation and vulnerability to shear stress, hinder their applications. Through composite modification and structural design strategies, a three-layer structured MXene-carbon nanotubes hybrid film (tHCM) is fabricated, exhibiting a tensile strength and fracture strain of 153.8 MPa and 4.65 %, respectively, representing improvements of 598.4 % and 226.8 % compared to the initial film. Meanwhile, the film maintains excellent stability demonstrating the enhancing effects of hydrogen bonds and densely packed structure. The hybrid films demonstrate unique and facile welding features due to splicing properties, enabling the formation of complex configurations. In terms of electro-/photo-thermal conversion performance, the hybrid film can reach a reasonably high temperature of 250 °C at low voltage (2.5 V) and 110.6 °C under 150 mW cm-2 infrared light. Leveraging the thermal expansion mismatch between tHCM and thermoplastic films, an integrated, flexible, and weldable actuator with unique electro/photo-response is developed, and various biomimetic driving applications, particularly, the light-mediated hierarchical transmission and precise motion along predetermined trajectory are realized. This work not only provides an effective strategy for modifying MXene composite films but also advances the design of novel actuators, offering broad application prospects in fields such as stimulus-responsive actuated robots and cargo transportation.

Making titanium alloys ultrahigh strength and toughness synergy through deformation kinks-mediated hierarchical α-precipitation Keer Li, Wei Chen, Jinyu Zhang, Shewei Xin, Jun Sun J. Mater. Sci. Technol.    2025, 207: 142-159.   DOI: 10.1016/j.jmst.2024.04.035 Abstract （111）      PDF       Knowledge map    Titanium alloys engineered in structural applications achieve ultrahigh strength primarily through precipitation strengthening of secondary α-phase (αs) during aging, while they often experience compromised ductility and toughness due to traditional strength-toughness tradeoff. In this study, we propose a novel strategy to address this conflict by introducing deformation kinks prior to conventional cold rolling (CR) and aging processes. These kinks are produced by cold forging (CF) to create macroscopic lamellar structures in β-grains, which alter strain partitioning during subsequent CR and ultimately tailor αs-precipitation upon aging. As a result, an ultrafine duplex (αe + β)-structure is formed within kink interiors, while hierarchical αs-precipitates are generated in the external β-matrix. This unique microstructure effectively enhances dislocation activity, promotes uniform plastic strain distribution and impedes crack propagation. Consequently, a simple Ti-V binary titanium alloy exhibits exceptional properties with ultrahigh strength ～1636 MPa, decent ductility ～5.4 % and appreciable fracture toughness ～ 36.1 MPa m½. The synergetic properties surpass those obtained through traditional CR and aging processes for the alloy and even outperform numerous multielement engineering titanium alloys reported in literature. Our findings open up a new avenue for overcoming the strength-toughness tradeoff of ultrahigh-strength titanium alloys, and also offer a facile production route towards structural materials for advanced performance.

Significantly ameliorating room-temperature brittleness of refractory high-entropy alloys via in situ heterogeneous structure Dong Han, Baijun Yang, Wenlong Xu, Hongwang Yang, Guofeng Han, Xiaoming Wang, Jianqiang Wang J. Mater. Sci. Technol.    2024, 193: 1-17.   DOI: 10.1016/j.jmst.2024.01.022 Abstract （111）      PDF       Knowledge map    Although refractory high-entropy alloys (RHEAs) possess excellent softening resistance and thermal stability at high temperatures, their practical application is often limited due to room temperature (RT) brittleness. In this work, we successfully achieved RT plasticization in a brittle (TaMoTi)92Al8 RHEA via in situ forming heterogeneous structure (HS) with the doping of Zr. Different from the mainstream design concept of “soft solid solution matrices with hard intermetallic phases” proposed in the literature, the newly developed TaMoZrTiAl RHEA is featured by a hard disordered BCC phase embedded into a soft intermetallic B2 matrix. Such an HS leads to the remarkable strength-plasticity synergy in this alloy at RT, showing a large plasticity of > 20 %, associated with a high strength of > 2380 MPa. It was found that solid solution strengthening and heterodeformation-induced strengthening caused by dislocation pile-ups at phase boundaries are responsible for the enhancement in the yield strength, while deformation-induced strain partition and the frequent operation of dislocation cross-slip substantially improve the work hardening capacity of alloy, thus enabling the high strength and good RT plasticity. In short, the current work not only reveals the micromechanisms of the influence of heterogeneous dual-phase structure on the RT mechanical behaviour in RHEAs but also provides a useful strategy for plasticizing brittle RHEAs.

Yue, J. Hou, H.J. Huang, G.P. Xu, S.J. Li, A.H. Feng, C.Y. Teng, A.J. Huang, L.-C. Zhang, D.L. Chen J. Mater. Sci. Technol.    2024, 198: 111-136.   DOI: 10.1016/j.jmst.2024.01.086 Abstract （104）      PDF       Knowledge map    Additive manufacturing features rapid production of complicated shapes and has been widely employed in biomedical, aeronautical and aerospace applications. However, additive manufactured parts generally exhibit deteriorated fatigue resistance due to the presence of random defects and anisotropy, and the prediction of fatigue properties remains challenging. In this paper, recent advances in fatigue life prediction of additive manufactured metallic alloys via machine learning models are reviewed. Based on artificial neural network, support vector machine, random forest, etc., a number of models on various systems were proposed to reveal the relationships between fatigue life/strength and defect/microstructure/parameters. Despite the success, the predictability of the models is limited by the amount and quality of data. Moreover, the supervision of physical models is pivotal, and machine learning models can be well enhanced with appropriate physical knowledge. Lastly, future challenges and directions for the fatigue property prediction of additive manufactured parts are discussed. Reference | Related Articles | Metrics

Simultaneously enhancing strength and ductility of LPBF Ti alloy via trace Y2 O3 nanoparticle addition Yinghang Liu, Zhe Song, Yi Guo, Gaoming Zhu, Yunhao Fan, Huamiao Wang, Wentao Yan, Xiaoqin Zeng, Leyun Wang J. Mater. Sci. Technol.    2024, 191: 146-156.   DOI: 10.1016/j.jmst.2024.01.011 Abstract （103）      PDF       Knowledge map    Laser powder bed fusion (LPBF) is a popular additive manufacturing (AM) technique to fabricate metal components. LPBF Ti alloys often exhibit high strength but poor ductility. In this study, we report that trace Y2 O3 nanoparticles added to a pre-alloyed Ti-4Al-4V (Ti44) powder provides an excellent feedstock for LPBF. As-built Ti44-Y2 O3 materials exhibited a strength-ductility combination that is slightly better than heat-treated LPBF Ti64. Some Y2 O3 particles may have melted or decomposed during LPBF. From electron microscopy, the addition of Y2 O3 refined α’ martensite laths and weakened variant preference during β→ α’ transformation. Based on in situ synchrotron X-ray diffraction and elastic-viscoplastic self-consistent (EVPSC) modeling, ?c+a? slip was more active in as-built Ti44-Y2 O3 than in as-built Ti64 or Ti44. This work demonstrates that LPBF can be an excellent method to fabricate metal-nanoparticle composite materials. Reference | Related Articles | Metrics

High impact toughness of CT20 alloy induced by multi-factor coupling Runqi Zhang, Qinyang Zhao, Dizi Guo, Yang Ying, Huan Wang, Zhongli Qiao, Yunbo Zhang, Lin Wang, Yongqing Zhao J. Mater. Sci. Technol.    2024, 192: 65-81.   DOI: 10.1016/j.jmst.2023.11.078 Abstract （100）      PDF       Knowledge map    Impact deformation behaviors of CT20 alloy with lamellar microstructure (LM), equiaxed microstructure (EM) and bimodal microstructure (BM) at room temperature were systematically investigated in this study. The experimental results indicated the excellent mechanical properties of CT20 alloy with BM under dynamic load. The impact toughness of BM specimen (～118 J/cm2) is ～17.5 % higher than that of LM specimen and ～33.8 % higher than that of EM specimen. The impact energy of EM specimen is the lowest due to the relatively simple equiaxed microstructure. LM specimen can absorb the highest crack initiation energy due to the best twinning ability. The highest impact toughness of BM specimen is induced by multi-factor coupling during impact deformation. Finer initial equivalent grain size, smaller lamellar thickness, lamellar induces twinning, finer twins, crack propagation path, and interaction between twins and β lamellar are all factors affecting impact toughness.

Tailoring precipitate distribution in 2024 aluminum alloy for improving strength and corrosion resistance Yong Zhang, Lantian Zhang, Xiang Gao, Xulong An, Le Zong, Zhihong Jia, Hao Zhou, Yudong Sui, Wenwen Sun J. Mater. Sci. Technol.    2024, 194: 16-27.   DOI: 10.1016/j.jmst.2023.12.055 Abstract （98）      PDF       Knowledge map    For the traditional peak-aged (PA) AA2024 alloy, the formation of large S-phase precipitates within the grains, wide precipitate-free zones (PFZs) near the grain boundaries (GBs), and continuous distribution of grain boundary precipitates (GBPs) can be observed. As a result, the PA alloy exhibits relatively high strength but poor corrosion resistance. However, with the application of cyclic plasticity treatment, high-density 1-2 nm clusters form within the matrix, and no PFZs form near GBs. In this study, this treatment yields the optimal balance between strength-elongation characteristics and corrosion resistance. By combining cyclic plasticity and ageing heat treatment with different heating rates, the nanoscale clusters play a crucial role as heterogeneous nucleation sites, resulting in the formation of finer and higher number density of S precipitates within the matrix. Additionally, the presence of these clusters reduces the formation of GBPs and minimizes the width of PFZs. Consequently, compared to the traditional PA sample, this approach achieves a significantly higher yield strength (increased by 46 %) and ultimate tensile strength (increased by 18 %), along with superior corrosion resistance. Although the influence of ageing heat treatment with different rates on mechanical properties is not significant, it notably affects the formation of GBPs and corrosion resistance. Specifically, a slower heating rate leads to an increase in the spacing between adjacent GBPs, resulting in improved corrosion resistance. In summary, cyclic strengthening, as a novel method for alloy strengthening, when combined with ageing heat treatment, modulates the distribution of S precipitates within the matrix and GBs. This optimization maximizes the effects of precipitation strengthening and breaks the inverse relationship between strength and corrosion resistance. Reference | Related Articles | Metrics

The addition of non-halogen flame retardants (FRs) including aluminum trihydroxide (ATH), triphenyl phosphate (TPP), and diammonium phosphate (DAP) leads to markedly enhanced thermal stability and fire resistance of the PU/nSiO2/FRs nanocomposites, resulting in achieving UL-94 HB standard. In particular, the nanocomposites met the UL-94 V-0 criteria thanks to the inclusion of DAP at 25 phr. The LOI value of the nanocomposites reached 26 % which is much higher than that of PU/nSiO2 nanocomposite, about 20 %. In order to further understand the fire-proof mechanism, the residue char layer remaining of the PU/nSiO2/FRs nanocomposites after being burned was also investigated by scanning electron microscopy (SEM) and Fourier transform infrared (FTIR). In addition, the microstructure, thermal stability, thermal conductivity, and mechanical properties of nanocomposites were also evaluated in this study. Reference | Related Articles | Metrics

Microscopic and mesoscopic deformation behaviors of dual-phase Mg-Li-Gd alloys Jing Li, Li Jin, Fulin Wang, Chuhao Liu, Huamiao Wang, Jie Dong J. Mater. Sci. Technol.    2024, 194: 1-15.   DOI: 10.1016/j.jmst.2023.12.064 Abstract （88）      PDF       Knowledge map    The Mg-Li dual-phase alloys, comprised of hexagonal (HCP) and body-centered cubic (BCC) phases, exhibit a better combination of strength and ductility than Mg single-phase alloys. In this work, the deformation behaviors of Mg-6Li-2Gd and Mg-2Gd alloys, representatives of dual-phase and single-phase alloys, have been studied at both microscale and mesoscale to elucidate the underlying mechanisms. Nanoindentation results show that the α-Mg phase in the Mg-6Li-2Gd alloy is harder than the β-Li phase. The intergranular deformation incompatibility, which arises from the elastic-plastic interactions, different strain accommodation behaviors, and strain hardening behaviors between the hard α-Mg phase and the soft β-Li phase, leads to pronounced hetero-deformation induced (HDI) stress of the Mg-6Li-2Gd alloy. The HDI stress strengthens the two phases simultaneously, so that the yield strength of the dual-phase Mg-6Li-2Gd alloy is higher than the Mg-2Gd alloy as well as the harder α-Mg phase in the Mg-6Li-2Gd alloy. Due to the decreased strength difference between the two phases caused by the HDI stress strengthening, the dual-phase alloy exhibits homogeneous plasticity at the mesoscale, which benefits the elongation of the Mg-6Li-2Gd alloy. The HDI strengthening magnitude in the Mg-6Li-2Gd alloy is further quantified. Based on the equal strain upper bound and equal stress lower bound approximations, the yield strength improved by the HDI stress is estimated to be 18-37 MPa, which is in the same range as the elastic visco-plastic self-consistent (EVPSC) simulation results. As the tensile strain is larger than ～3 %, the HDI strengthening magnitude for the Mg-6Li-2Gd alloy reaches 50-65 MPa, accounting for 35 % of the corresponding flow stress.

Interfacial coherence regulation and stabilization of molybdenum/Kovar alloy welded joint by CoCrCuFeNi high entropy alloy Qianxing Yin, Guoqing Chen, Xinyan Teng, Yang Xiang, Xuesong Leng J. Mater. Sci. Technol.    2024, 194: 43-50.   DOI: 10.1016/j.jmst.2024.02.001 Abstract （88）      PDF       Knowledge map    The crux of molybdenum/Fe-base alloy welded joint is embrittlement and consequently deteriorated strength. The current researches just attribute it to brittle intermetallic compound inside the weld. However, no brittle phase continuously precipitates at the fracture location of the molybdenum/Kovar alloy electron beam welded joint, meaning that the unstable phase interface is the real fundamental reason for the brittleness of joint, instead of the phases themselves. Noncoherent interfaces are formed between α-Mo and eutectoid α-Fe + μ(Fe3Mo2) deriving from solid-state phase transition. To optimize interfacial coherence and stabilize the interface, CoCrCuFeNi high entropy alloy is added into the weld. The new interfaces between α-Mo and eutectic face-centered cubic (fcc) + laves are transformed into coherent interfaces. σ(FeCr) nanoparticles precipitate at α-Mo/fcc interface, indicating the decreased interfacial energy and more stable interface. The tensile strength of the joint is increased from 262 to 366 MPa. The present work provides guidance for optimizing welding quality between molybdenum and Fe-base alloy.

Ultrahigh temperature ablation resistant HfB2-SiC composites: From liquid SiHfCB precursor synthesis to light weight bulk preparation and characterization Yang Lyu, Jianchao Hao, Yuan Cheng, Wuju Wang, Zhihong Han, Guangdong Zhao, Ruichen Ni, Pu Liu, Hangyu Li, Guiqing Chen, Xinghong Zhang, Wenbo Han J. Mater. Sci. Technol.    2025, 212: 1-16.   DOI: 10.1016/j.jmst.2024.04.080 Abstract （85）      PDF       Knowledge map    The current generation of ultrahigh temperature ceramic precursors typically encounters obstacles in achieving high ceramic yields (<40 wt.%) due to the challenges in integrating significant amounts of boron, which hampers their conversion into boride-based ultrahigh temperature ceramics. To tackle these challenges, a serious of pioneering liquid multi-component hafnium-containing ceramic SiHfCB precursors (with different Hf/Si ratios) have been developed. These novel precursors are featured with stable molec-ular structure and high ceramic yield which were successfully created through a novel one-pot polymer-ization process. They present in liquid form and their structure is characterized by C-C bonds forming its main chain with branched chains of O-Si-O, Si-O-Hf, Si-O-B, and B-O-Hf which have untapped advantages including uniform component dispersion, and excellent fluidity. The ceramic yield of SiHfCB precursor with Hf/Si of 0.2 is remarkably up to 68.6 wt.% at 1500 ℃, and their Hf content exceeded 50 wt.%. Of particular interest, the pyrolyzed product HfB2-SiC nanopowders derived from the SiHfCB precursor with Hf/Si of 0.2, consist of nanopowders in the 40-60 nm range with a density of 5.23 g cm-3. Remarkably, this material demonstrates exceptional performance in ultrahigh temperature oxygen-containing environ-ments at 2500 ℃, showing near-zero ablation with a linear ablation rate of just 2.5 × 10-4 mm s-1. Post-ablation analysis of the microstructure reveals that the formation of a lava-like HfO2 and HfO2-SiO2 oxide layer effectively blocks oxygen penetration and provides excellent oxidation resistance. The inno-vative SiHfCB hafnium-containing ceramic precursor offers a groundbreaking solution for the preparation of lightweight ultrahigh-temperature ceramics. This development is poised to provide robust technical support for the use of ultrahigh temperature ceramics in non-ablative thermal protective systems, partic-ularly in the construction of hypersonic vehicles, where ultrahigh temperature resilience is crucial.

Microstructure inheriting evolution and strength-plasticity collaborative improvement mechanism of multidirectional rotary forged Al7075 sheets during T6 heat treatment Xuan Hu, Xinghui Han, Lin Hua, Jishi Zhang, Jing Xu, Fang Chai, Wuhao Zhuang, Fangyan Zheng J. Mater. Sci. Technol.    2024, 203: 14-38.   DOI: 10.1016/j.jmst.2024.03.043 Abstract （84）      PDF       Knowledge map    Al7075 sheets are widely used in aerospace industry and their higher strength-plasticity collaborative improvement requirement is urgent. In this study, the microstructure inheriting the evolution and mechanical properties of Al7075 sheets during multidirectional rotary forging (MRF) and T6 heat treatment are analyzed. The results show that the average grain size exhibits near-parabolic evolution with increasing MRF deformation amount. MRF20 %+T6 (20 % MRF deformation amount+T6) condition possesses the largest grain size of 72.6 μm, and its abnormal grain growth mechanism is that the medium deformation energy and high deformation heterogeneity in MRF20 % deformed grains could cause asynchronous recrystallization behavior during T6 heat treatment, and the grains with comparatively higher deformation energy get recrystallized firstly and devour adjacent grains along preferred 〈011〉 or 〈223〉 misorientation axis. MRF70 %+T6 condition possesses the finest grain size of 14.2 μm, and its fine grain inheriting mechanism is that the uniformly high deformation energy in MRF70 % deformed grains causes uniformly rapid recrystallization, and rapidly recrystallized grains effectively suppress grain boundary motion from adjacent grains. With increasing MRF deformation amount, tensile strength and elongation values both exhibit near-antiparabolic evolution. MRF70 %+T6 condition possesses the largest tensile strength (563 MPa) and elongation (17.73 %), which increases by 8.27 % and 80.55 % compared to as-annealed+T6 (MRF0 %+T6) condition (tensile strength is 520 MPa and elongation is 9.82 %), respectively. The strength-plasticity collaborative improvement is mainly because the combination of effectively inherited fine grains, refined inclusion particles, and uniformly distributed fine η' particles after T6 heat treatment could promote smooth dislocation movement and coordinated slip behavior in most matrix grains, which contributes to the delay of stress localization and strength-plasticity collaborative improvement.

Ultrafast nanomanufacturing via high-temperature shock of La0.6 Sr0.4 CoO3 catalysts for overall water splitting Xiaoya Cui, Wenyu Li, Yanchang Liu, Yumei Zhu, Yanan Chen, Cairong Gong, Gang Xue J. Mater. Sci. Technol.    2024, 191: 1-7.   DOI: 10.1016/j.jmst.2023.11.067 Abstract （84）      PDF       Knowledge map    Electrochemical water splitting, as an effective sustainable and eco-friendly energy conversion strategy, can produce high-purity hydrogen (H2) and oxygen (O2) via hydrogen evolution reaction (HER) and oxy-gen evolution reaction (OER), respectively, altering the nonrenewable fossil fuels. Here, La0.6 Sr0.4 CoO3 per-ovskite oxide nanoparticles with an orthorhombic phase were synthesized within 2 min in a one-step reaction, using a rapid and efficient high-temperature shock (HTS) method. Impressively, the as-prepared La0.6 Sr0.4 CoO3 with orthorhombic phase (HTS-2) exhibited better OER and HER performance than the hexagonal phase counterpart prepared using the traditional muffle furnace calcination method. The elec-trocatalytic performance enhancement of orthorhombic La0.6 Sr0.4 CoO3 can be attributed to the novel or-thorhombic structure, such as confined strontium segregation, a higher percentage of highly oxidative oxygen species, and more active sites on the surface. This facile and rapid synthesis technique shows great potential for the rational design and crystal phase engineering of nanocatalysts. Reference | Related Articles | Metrics

Mater. Sci.

The PSN-PMN-PT textured ceramic with a Lotgering factor F001 higher than 99% was synthesized by the liquid-phase-assisted template grain growth (TGG) method. The addition of CuO/B2O3 sintering aids improves the BT templates induced grain orientation growth behavior significantly. In comparison with its random counterpart, the Cu/B-T textured ceramic exhibits a high Lotgering factor F001 of 99% and significantly enhanced dielectric and piezoelectric responses: εr ～ 3100, tanδ ～ 0.8%, d33 ～ 1030 pC N-1, d33?g33 ～ 34.2 × 10-12 m2 N-1, d33* ～ 1490 pm V-1@5 kV cm-1, Smax ～ 0.26%@20 kV cm-1 and Hs ～ 8.5%. In the meantime, good temperature stability is observed in the Cu/B-T textured ceramic with a variation of d33*@20 kV cm-1 and annealed d33 lower than 9.68% and 18.1% over a wide temperature range of 25-140 °C. This work shows that PSN-PMN-PT textured ceramic (Cu/B-T) has great potential for electromechanical device applications such as precision actuators, ultrasound transducers, and energy harvesters.

Mechanisms of plastic deformation and mechanical strengthening in nano-scale Ti-Ti2Cu eutectoids: A study combined molecular dynamics simulation and experiment Haodong Wang, Chun Yu, Moqiu Li, Yi Zheng, Junmei Chen, Jieshi Chen, Hao Lu, Jijin Xu J. Mater. Sci. Technol.    2024, 193: 146-159.   DOI: 10.1016/j.jmst.2023.12.044 Abstract （81）      PDF       Knowledge map    Ti-Cu eutectoid or near-eutectoid alloys were found to possess exceptional high strength owning to the nano-scale lamellar structure of Ti2Cu and α-Ti after additive manufacturing, they are potential candidates for high-performance materials. To reveal the deformation and strengthening mechanisms, the molecular dynamics (MD) simulations and experimental analysis were carried out upon Ti-Ti2Cu lamellae. In this work, we focused on revealing the interface dislocations (IDs) pattern and its effects on the dynamic evolution of the lattice dislocations (LDs) at the Ti/Ti2Cu interface with (0001)a//(013)Ti2Cu orientation relationship. Atomistic simulations depicted that the equilibrium Ti/Ti2Cu interface contains three groups of partial dislocations which dictate two interfacial coherent structures with low stacking fault energy. Each ID consists of several segments, connected by atomic steps with identical direction. The nucleation sites of LDs under external loading locate at the intersection between the dislocation segment and the atomic step, which is related to the local high atom strain. Under compression deformation, the <100> {011} and <331> {103} slip systems in Ti2Cu, and the <1123> {1011} slip system in α-Ti are activated, achieving a co-deformation mechanism in the Ti-Ti2Cu multilayers. The dislocation-interface interactions are responsible for the deformation plasticity and in turn governs the mechanical strengthening. During nanoindentation tests, larger hardness (～6.2 GPa) and smaller activation volume (～12b3) were found in the Ti-Ti2Cu lamellae, which is mainly ascribed to the presence of high-density lamellae interface and confined layer slip, resulting in interface-mediated dislocation annihilation/deposition and consequent high strain hardening. The MD simulations, nanoindentation tests and TEM investigations of interlayer dislocation activity support the strengthening mechanism of dislocation-interface interactions.

NIR-light-induced plasmonic liquid metal/ionic liquid/MXene polyurethane films with excellent antifouling and self-healing capabilities Peng Wang, Haohang Yuan, Baoluo He, Ruisheng Guo, Shujuan Liu, Qian Ye, Feng Zhou, Weimin Liu J. Mater. Sci. Technol.    2025, 221: 1-10.   DOI: 10.1016/j.jmst.2024.09.034 Abstract （79）      PDF       Knowledge map    The potential of organic coatings in antifouling applications has been well-documented. Beyond their exceptional antifouling effects, these coatings should also possess good mechanical strength and self-healing capabilities. Herein, a novel vinyl-based ionic liquid [VEMIM+] [Cl-] (IL) was in situ polymerized and then assembled onto the surface of liquid metal (GLM) nanodroplets to prepare GLM-IL. Subsequently, Ti3C2Tx (MXene) was modified with GLM-IL nanodroplets to obtain GLM-IL/MXene composite, which acts as an efficient photon captor and photothermal converters and can be further composited with PU film (GLM-IL/MXene/PU). Notably, the composite film significantly increases by ～117 °C after exposure to 200 mW/cm2 light irradiation. This increase is attributed to the high photothermal conversion efficiency of MXene and the excellent plasma effect of GLM-IL. Compared with pure PU, the GLM-IL/MXene/PU film shows a 50 % improvement in tensile strength and above 85.8 % healing efficiency with a local temperature increase. Additionally, the as-prepared GLM-IL/MXene/PU film reveals satisfactory antifouling properties, achieving a 99.7 % reduction in bacterial presence and an 80.3 % reduction in microalgae. This work introduces a novel coating with antifouling and self-healing properties, offering a wide range of applications in the fields of marine antifouling and biomedicine.

Strength-plasticity matching regulation of cold rotary forged Al5A06 sheets by annealing treatment and its influence on fatigue property Xuan Hu, Xinghui Han, Lin Hua, Fang Chai, Wuhao Zhuang, Fangyan Zheng, Fei Yin, Xiaokai Wang J. Mater. Sci. Technol.    2024, 192: 123-148.   DOI: 10.1016/j.jmst.2024.01.020 Abstract （79）      PDF       Knowledge map    Al5A06 sheets by large cold plastic deformation usually have high strength but low plasticity, i.e. weak strength-plasticity matching, which may lead to their poor fatigue property. In this study, annealing treatments are applied on cold rotary forged Al5A06 sheets to regulate strength-plasticity matching and improve fatigue properties. The microstructures, tensile mechanical properties and fatigue properties under different annealing parameters were analyzed. The abnormal grain growth mechanism of cold rotary forged Al5A06 sheets during 300 °C annealing treatment was investigated, and the fatigue failure mechanism of Al5A06 sheets with different annealing temperatures was also investigated. The abnormal grain growth during 300 °C annealing treatment is mainly due to the asynchronous recrystallization behavior with low recrystallization driving force, which leads to the early recrystallized regions directly absorbing adjacent grains along 〈134〉 crystal direction. The cold rotary forged Al5A06 sheets after 250 °C-2 h annealing treatment exhibit the best fatigue property, which is mainly because the optimum strength-plasticity matching brings about coordinate plastic deformation throughout most grains, and the effective dislocation movement between adjacent grains can delay the appearance of strain localization and accommodate continuous fatigue cyclic loading.

Biochar decorated Bi4O5Br2/g-C3N4 S-scheme heterojunction with enhanced photocatalytic activity for Norfloxacin degradation Chao Chen, Xiaofei Zhang, Enzhou Liu, Jingsan Xu, Jing Sun, Huanxian Shi J. Mater. Sci. Technol.    2024, 198: 1-11.   DOI: 10.1016/j.jmst.2024.01.063 Abstract （76）      PDF       Knowledge map    In this work, a novel biochar decorated Bi4O5Br2/g-C3N4 S-scheme heterojunction was successfully prepared for Norfloxacin (NOR) degradation, and it was found that the 5 %-Bi4O5Br2/g-C3N4/C heterojunction exhibited the excellent photocatalytic degradation activity toward NOR, degrading 92.5 % of NOR within 72 min under visible light irradiation. The effects of pH, dosage, and concentration of the NOR on the photocatalytic activity were also systematically investigated. The mechanism studies revealed that the active species like hole (h+), hydroxyl radical (·OH), and superoxide radical(·O2-) play a predominant role in the NOR degradation, and the enhanced removal rate of Bi4O5Br2/g-C3N4/C heterojunction can be attributed to the synergistic effect of adsorption and photocatalytic process. In addition, an S-scheme transfer channel in the interface of the Bi4O5Br2/g-C3N4/C heterojunction is proposed, which can effectively improve the separation of the photogenerated carriers and enhance the photocatalytic performance. This research provides inspiration for designing S-scheme heterojunction for wastewater treatment. Reference | Related Articles | Metrics

Microstructure and mechanical properties of cast Al-Li-Mg alloy: Role of Cu addition and heat treatment Fangzhou Qi, Guohua Wu, Liang Zhang, Xin Tong, Xuanxi Xu, Youjie Guo J. Mater. Sci. Technol.    2024, 199: 1-16.   DOI: 10.1016/j.jmst.2023.12.076 Abstract （76）      PDF       Knowledge map    In this work, the effect of Cu addition and heat treatment schemes on the microstructural evolution, mechanical properties, and corresponding strengthening mechanism of cast Al-Li-Mg alloy were investigated. Results indicate that the dendritic segregation would be induced after the introduction of Cu, and a well-designed two-stage solution treatment could effectively dissolve secondary phases. With Cu addition, aging hardening responses of the alloys were accelerated, accompanied by a continuous increase in the volume fraction of both S'-Al2CuMg and Al3Li phases, which enhanced the precipitation strengthening effect. Furthermore, in Cu-containing alloys, both the coarsening of Al3Li phases and the expansion of Al3Li-precipitation free zones (PFZ) were inhibited during the aging process. However, severe strain accumulation was found at the interface between the coalesced S' phase and α-Al matrix, which reduced the ductility of the alloy. A good combination of strength and ductility (YS = 308 MPa, UTS = 428 MPa, EL = 5.0 %) was obtained in the Al-2.5Li-2Mg-1Cu-0.12Zr alloy aged at 175 °C for 32 h due to the narrowed Al3Li-PFZ and the synergistic strengthening of Al3Li and S' phase. This work is expected to provide guidelines for designing novel cast Al-Li alloys with wider applications. Reference | Related Articles | Metrics

Liquid metal assistant self-propagating high-temperature synthesis of S-containing high-entropy MAX-phase materials Donglong Bai, Qiang Wang, Bin Deng, Yang Li, Ao Huang, Zitong Cheng, Yun Zhao, Jing Li, Yang Li, Wei Yao, Jianguang Xu J. Mater. Sci. Technol.    2025, 209: 1-8.   DOI: 10.1016/j.jmst.2024.05.006 Abstract （74）      PDF       Knowledge map    Due to their high-entropy effects, the high-entropy (HE) MAX-phase materials improve the comprehensive performance of MAX phases, opening up more possibilities for practical engineering applications. However, it is still challenging to obtain S-containing high-entropy MAX phases because of the high volatilization behavior of sulfur, suffering from issues such as high reaction temperature and long reaction time of traditional synthesis methods. This paper proposes a novel process named as liquid metal assistant self-propagating high-temperature synthesis (LMA-SHS) for efficient synthesis of high-purity S-containing high-entropy MAX-phase materials. Low-melting-point metal (Sn or In) has been introduced into the raw mixture and melted into a liquid phase during the early stage of the SHS reaction. By serving as a “binder” between transition metal atoms of the M-site due to the negative mixing enthalpy, this liquid phase can accelerate mass and heat transfer during the SHS process, ensuring a uniform solid solution of each element and realizing the synthesis of high-purity (TiNbVZr)2SC in an extremely short time. The synthesis method for high-entropy MAX-phase materials developed in this study, i.e., LMA-SHS, showing very short reaction time, low energy consumption, high yield, and low cost, has the promise to be a general energy- and resource-efficient route towards high-purity HE materials.

Mater. Sci. Technol.    2025, 218: 1-24.   DOI: 10.1016/j.jmst.2024.08.029 Abstract （72）      PDF       Knowledge map    Electrocatalytic CO2 reduction (ECR) is a promising approach for achieving carbon neutrality due to its ability to convert CO2 to valuable chemicals. Recent advances have significantly enhanced the ECR performance of various catalysts by tuning their oxidation states, particularly for Cu-based catalysts that can reduce CO2 to multiple products. However, the oxidation state of copper (OSCu), especially Cu+, changes during the reaction process, posing significant challenges for both catalyst characterization and performance. In this review, the current understanding of the effect of oxidation states on product selectivity was first discussed. A comprehensive overview of in situ/operando characterization techniques, used to monitor the dynamic evolution of oxidation states during ECR, was then provided. Various strategies for stabilizing oxidation states through modification of catalysts and manipulation of external conditions were discussed. This review aimed to deepen the understanding of oxidation states in ECR and enlighten the development of more efficient electrocatalysts. Reference | Related Articles | Metrics

Influence of rare earth elements (Y, La and Ce) on the mechanical properties and oxidation resistance of nickel-based superalloys: A critical review J.G. Li, N. Wang, J.D. Liu, W. Xu J. Mater. Sci. Technol.    2024, 195: 9-21.   DOI: 10.1016/j.jmst.2023.11.077 Abstract （71）      PDF       Knowledge map    Rare-earth elements (REEs) received special attention and widespread application because of their extremely active chemical property. Many researches demonstrated that doping of REEs (Y, La and Ce) in superalloys can significantly improve the high temperature oxidation resistance, corrosion resistance and mechanical properties, which are recognized as a promising route to broaden the manufacturing process window and enhance the overall performance of next-generation superalloys.

An asymmetric Janus membrane with anti-bacteria adhesion and rapid hemostasis properties for wound healing Zihe Hu, Gaoying Hong, Mumian Chen, Haiyan Wu, Weiying Lu, Yuewei Chen, Zhijian Xie, Changyu Shao, Jue Shi J. Mater. Sci. Technol.    2024, 192: 201-214.   DOI: 10.1016/j.jmst.2023.11.048 Abstract （71）      PDF       Knowledge map    Currently, commercial intraoral dressings have limitations as they only serve a single purpose and fail to meet various needs, such as hemostasis, wound protection, and dressing fixation. Here, we successfully fabricated a multifunctional polycaprolactone-chitosan Janus membrane (PCJM) with simultaneous hydrophobic and hydrophilic properties. The hydrophobic layer consists of a dense and disordered polycaprolactone, preventing bacterial adhesion, resisting fouling, and enhancing mechanical strength. The hydrophilic layer is a highly porous chitosan sponge, which facilitates cell and protein adhesion, as well as rapid absorption of blood and activation of the coagulation process. These results are confirmed by hemostasis experiments, which demonstrate that the PCJM had superior coagulation ability compared to commercial gelatin sponges and gauze, and by an early gingival healing model of beagle tooth extraction wounds, which exhibited excellent performance in promoting wound healing. Our work demonstrates the multifunctional PCJM wound dressing not only protects wounds from bacterial infections but also facilitates rapid hemostasis and early healing of beagle gingival soft tissue, which holds significant potential for clinical translation and large-scale production.

Determination of interfacial heat transfer coefficient at the frozen sand mold casting process of ZL101 alloy Shijie Dong, Zhongde Shan, Feng Lin, Haoqin Yang, Xiao Liang J. Mater. Sci. Technol.    2024, 194: 28-42.   DOI: 10.1016/j.jmst.2024.01.032 Abstract （68）      PDF       Knowledge map    Compared to the resin sand mold casting process, frozen casting is more environmentally friendly, providing a better working environment and enhanced supercooling degree. The interfacial heat transfer coefficient (IHTC) between frozen sand mold and metal is an important parameter that significantly influences the final mechanical properties and microstructure of the castings. This paper solved the inverse heat conduction problem using the finite difference method (FDM). In addition, the conjugate gradient method (CGM) was adopted to calculate the temperature distribution and heat flux in the molten metal. At the same time, the particle swarm optimization algorithm (PSO) was used in temperature distribution determination in frozen sand mold. The interfacial heat transfer coefficient (IHTC) was estimated during the solidification of ZL101. The results showed a good agreement between calculated and experimental data, obtaining accurate casting interface temperature Tm, frozen sand mold interface temperature Ts, heat flux q, and IHTC. The analysis of the IHTC variation revealed a water content value within the range of 4 wt.% to 5 wt.% resulted in IHTC in two types of interpretation, called ‘fluctuation type’ and ‘turning type’.

Structure evolution and τf influence mechanism of Bi1-xHoxVO4 microwave dielectric ceramics for LTCC applications Huaicheng Xiang, Yuheng Zhang, Junqi Chen, Yang Zhou, Ying Tang, Jinwu Chen, Liang Fang J. Mater. Sci. Technol.    2024, 197: 1-8.   DOI: 10.1016/j.jmst.2024.01.070 Abstract （68）      PDF       Knowledge map    Bi1-xHoxVO4 (0.1 ≤ x ≤ 0.9) ceramics were prepared via a solid-state reaction method, and all the ceramics could be well densified in the 920-980 °C range. The ceramics with 0.1 ≤ x < 0.4 were composed of both monoclinic scheelite (M) and tetragonal zircon (T) phases, and a single M phase could be obtained in the range of x ≥ 0.4. The measured εr decreased from 58.9 (x = 0.1) to 14.7 (x = 0.9), so do the calculated values (εr(C - M) = 34.3-12.1), and the main reason for εr > εr(C - M) was the rattling of Ho3+ in the dodecahedron. Two points with zero τf appeared in Bi1-xHoxVO4 (0 ≤ x ≤ 1) ceramics, and the best microwave dielectric properties with εr = 16.6, Q × f = 18,400 GHz (f = 10.69 GHz), and τf = +3.29 ppm/°C were obtained in the Bi0.2Ho0.8VO4 ceramic. The change in temperature coefficient of ionic polarizability (ταm) caused by the rattling effect of cations is the physical essence that affects τf. Therefore, the rattling effect can be used as an effective mechanism to regulate τf in low-εr materials. Furthermore, there was no chemical reaction between Bi1-xHoxVO4 and Ag electrode, which indicates potential applications in low-temperature co-fired ceramic (LTCC) technology.

Bifunctional optical probe based on La3Mg2SbO9:Mn4+ phosphors for temperature and pressure sensing Zhanglin Chen, Songmo Du, Fei Li, Shijia Zhang, Shuo Zhao, Zhaobo Tian, Jie Zhang, Xuanyi Yuan, Guanghua Liu, Kexin Chen J. Mater. Sci. Technol.    2024, 194: 98-109.   DOI: 10.1016/j.jmst.2023.12.074 Abstract （66）      PDF       Knowledge map    Photoluminescent materials, serving as optical probes, constitute a significant medium for reliable remote sensing of fundamental state parameters such as temperature and pressure. Herein, we report a novel Mn4+-activated perovskite-type La3Mg2SbO9 phosphor (LMS:Mn4+) for bifunctional application in both thermometry and manometry. Upon excitation with 341 nm, LMS:Mn4+ (0.7 % Mn4+) emits a bright narrow-band red light peaking at 705 nm with an FWHM (full width at half maximum) of 32 nm. As a thermometer, when the temperature surpasses 298 K, non-radiative transitions from the 2Eg excited state lead to a sharp decrease in decay lifetimes with increasing temperature. This allows for lifetime-based luminescence thermometry with a relative sensitivity of 2.52 % K-1 at 391 K. Moreover, LMS:Mn4+ was processed into a temperature-sensing coating and its non-contact thermometry functionality was validated. In manometry applications, the LMS:Mn4+ probe experiences substantial pressure-dependent redshift with a sensitivity of 1.20 nm GPa-1 in the testing range of 9.48 GPa, which is about 3.3 times that of conventional ruby probes. Furthermore, its FWHM consistently remains below 37 nm, which contributes to a high reliability of pressure measurements. The above results indicate that the LMS:Mn4+ constitutes a promising bifunctional luminescence probe material in thermometry and manometry. Reference | Related Articles | Metrics

Mechanical recycling of PET containing mixtures of phosphorus flame retardants Jiuke Chen, Sithiprumnea Dul, Sandro Lehner, Milijana Jovic, Sabyasachi Gaan, Manfred Heuberger, Rudolf Hufenus, Ali Gooneie J. Mater. Sci. Technol.    2024, 194: 167-179.   DOI: 10.1016/j.jmst.2024.01.035 Abstract （66）      PDF       Knowledge map    Flame-retarded polymers, such as polyester textiles and sheets, are attracting attention with regard to their sustainability. Mechanical recycling is currently the most frequently used technique for improving the circularity of plastics. However, one complication of mechanical recycling is associated with the (still) inevitable mixtures of polymers and additives, which can influence material stability and significantly deteriorate the mechanical properties of recycled products. In this study, we aim to specifically investigate the interactions between mixtures of phosphorus flame retardants (FRs) in polyethylene terephthalate (PET) and evaluate their potential role in the mechanical recycling of melt-spun fibers. Two highly relevant commercial FRs, namely a DOPO-derivative (DOPO-PEPA or DP) and Aflammit PCO 900 (AF), are added to PET compounds as additives using a melt compounder. The melt stability of PET/FR compounds over extended processing time is assessed by chemical, thermal, and rheological measurements. DP shows a molecular lubrication effect, lowering the melt viscosity of PET, while AF promotes chemical changes (i.e., chain branching/crosslinking). Interestingly, a PET compound containing hybrid mixtures of DP/AF 20/80 (wt.%/wt.%) shows the most stable behavior at high temperatures under both nitrogen and air atmospheres, thus showing a synergistic effect. Most importantly, in a recycling scenario, the stabilization effect persists at diluted concentrations below the typical FR contents in PET. Multiple extrusion cycles are used to assess the repeated processing behavior of the compounds, and the mechanical properties and fire behavior of melt-spun fibers are compared before and after recycling. The results reveal that DP can maintain the mechanical performance of recycled PET/FR fibers, even if it is mixed (contaminated) with AF. Reference | Related Articles | Metrics

The influence of post-aging treatment on the microstructure and micromechanical behaviors of additively manufactured maraging steel investigated by in situ high-energy X-ray diffraction Yang Li, Jingyue Yu, Shilei Li, Shengjie Wang, Yang Ren, Ke Yang, Yan-Dong Wang J. Mater. Sci. Technol.    2024, 200: 1-12.   DOI: 10.1016/j.jmst.2024.02.044 Abstract （66）      PDF       Knowledge map    The microstructure evolution and micromechanical behaviors of additively manufactured 18Ni300 maraging steel for both as-printed and aged one were investigated using the in situ high-energy X-ray diffraction (HE-XRD) technique with uniaxial tensile tests. The investigations revealed that the volume fraction of reversed austenite increased as the annealing temperature rose. The maraging steel was strengthened by η-Ni3Ti precipitates, where the aged maraging steel had a higher UTS value of ～1860 MPa than ～1135 MPa in the as-printed one, but sacrificed more than half of ductility (from ～8.6 % to ～4.0 %). The austenite in aged steel presents more stability induced by the aging process than that in as-printed counterpart, which has a higher critical martensitic transformation stress of ～1200 MPa than that of ～780 MPa in as-printed steel. The austenite grains orientated with [200]//LD yield before the macro-yielding and preferential martensite transformation occurs. This study provides further insight into the intricated micromechanical responses of additively manufactured 18Ni300 maraging steel, enlarging the scope of its adaptation and application.
