In this study, the effects of modifying elements, specifically Sr and Li, on the twin characteristics and morphology of eutectic Si, as well as on the mechanical properties of a high-pressure die-casting Al-7Si alloy, are systematically investigated. The results show that the addition of modifying elements, particularly Li, significantly increases twin density and promotes extensive twin branching, leading to a transition of eutectic Si from a coarse flaky morphology to a finer and more homogeneous structure. Compared with the unmodified alloy, both Li-modified and Sr-modified alloys exhibit greater scatter in mechanical properties. For samples containing only small pores, defined as those with an area fraction of the largest pore on the fracture surface ≤ 0.2%, the modified alloys demonstrate higher strength and improved ductility relative to the unmodified alloy. The mechanisms underlying the enhanced strength-ductility synergy and the increased scatter in mechanical response are discussed.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"8 9-10 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147439897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, a distinct two-step transformation peak was observed for the first time in the Ti–Ni–Nb–Co alloy developed in this study after annealing at temperatures between 550 and 750°C. In-situ Transmission Electron Microscopy confirmed that both steps correspond to martensitic transformations, which occur sequentially in the core and periphery regions of the TiNi matrix. Atom Probe Tomography, precise composition characterization, was employed to analyze clusters/GPzones/precipitates in both regions for abnormal martensitic transformation. Annealing at 550°C, the core region contains numerous Ti-rich atomic clusters, while Guinier–Preston (GP) zones (averaging 28 atoms) dominate in the periphery region. At 650°C, the clusters in the core grow into larger GP zones with an average of ∼68 atoms, while the periphery region is primarily occupied by ∼10 nm precipitates. At 750°C, both regions form compositionally stable precipitates, though their number densities differ. Collectively, the distinct composition and state of the precipitates in the two regions dictate the occurrence of the two-step martensitic transformation. Simulation results indicate that Ti-rich clusters and GP zones will increase the martensitic transformation energy to 0.0038 and 0.0077 eV, respectively. The significant variation in the martensitic transformation energy barriers between different regions leads to distinct martensitic transformation temperatures, thereby inducing the two-step transformation. This study suggests that controlling the annealing process can create heterogeneous microstructures with localized transformation energy variations, providing a strategy for designing advanced smart materials with complex phase transformation sequences.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"86 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147393173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report that a fine-grained, strongly textured Mg-Mn alloy achieves a superior specific energy absorption (32.4 kJ kg⁻¹) under high-rate impact (1500 s⁻¹) along the extrusion direction, which is comparable to commercial TWIP-steel and 6061 aluminum alloy. The performance advantage is driven by the anomalously high hardening rate of 3.3 GPa (2 to 4 times that of other conditions), characterized by the “low-yield-steep-hardening” response triggered by the high rates. This behavior also deviates significantly from the descriptions of standard phenomenological Johnson-Cook (J-C) models. While the J-C model fails to capture this characteristic, a crystal plasticity finite element (CPFEM) model incorporating rate-insensitive twinning kinetics accurately reproduces it.

Here, we show that the electroactive bacterium Geobacter sulfurreducens (<em>G. sulfurreducens</em>) directly reduces TiO₂ in the passive film, driving passive-film thinning, accumulation of more reduced titanium oxides (Ti³⁺/Ti²⁺), and a marked increase in donor density and electronic conductivity. High-resolution microscope, X-ray photoelectron spectroscopy, and electrochemical analyses revealed a 50-fold increase in corrosion current density, reduced polarization and charge-transfer resistances, and pronounced pitting correlated with TiO₂ depletion. Genetic disruption of the outer-surface cytochrome OmcS significantly attenuated TiO₂ reduction, passive-film thinning, and corrosion kinetics, demonstrating that microbial extracellular electron transfer machinery mediates this process. <em>G. sulfurreducens</em> growth with hydrous TiO₂ as the sole electron acceptor confirmed that TiO₂ reduction is physiologically and thermodynamically feasible.

The development of efficient and environmentally friendly anti-fouling methods remains a long-term and challenging issue. A coating loaded with antifouling agents is currently the simplest and most effective way to address fouling problems. However, environmental hazards cannot be ignored. Inspired by the changes in the biofilm microenvironment during biofouling, this study developed an intelligent and environmentally friendly protective coating system by incorporating dual-responsive microcapsules and modified graphene oxide (GO) into a solvent-free waterborne epoxy resin. Polylactic acid microcapsules functionalized with poly-L-lysine (PLL) provided a pH/enzyme-triggered controlled release of natural antifouling agent butenolide, leveraging the protonated amino groups and enzyme-sensitive peptide bonds of PLL. GO was covalently modified with γ-aminopropyltriethoxysilane (KH550) to enhance dispersibility and stability, while the cerium dioxide nanoparticles were grown in situ on GO surfaces to form a redox protective layer. The synergistic combination endowed the coating with environmentally responsive antifouling and long-term anticorrosion performance. This approach offers a novel design strategy for producing high-performance marine protective coatings.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"237 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2026-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147392942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
