This work developed a controllable synthesis strategy based on the Mott-Schottky theory and Prussian blue analog precursors, successfully constructing a CoFe/Co₂P heterostructure by integrating bimetallic nanoalloys with phosphide semiconductors. Experimental characterization and theoretical calculations confirmed the continuous electron enrichment at the Co site. The low electronegativity of Fe, as the electron donor, expanded the interfacial work function difference (ΔΦ), and synergistically optimized the <em>d</em>-band electronic structure and intermediate adsorption by accelerating charge transfer kinetics. Consequently, the CoFe/Co₂P heterostructure exhibits superior multi-reaction activity compared to pure Co₂P and Co/Co₂P in the urea oxidation reaction, oxygen evolution reaction (OER), and hydrogen evolution reaction in alkaline media. In situ characterization further demonstrated that the urea molecule was directly oxidized at the CoFe/Co₂P interface site, avoiding the formation of the rate-limiting step CoOOH in the OER, which has rarely been mentioned in previous studies, thereby achieving faster kinetics at a significantly reduced potential. Accordingly, the assembled two-electrode urea oxidation-assisted hydrogen production electrolytic cell only requires 1.314 V to drive a current density of 10 mA cm⁻², which is lower than the overall water splitting (1.691 V). This research provides a new interface control strategy for the rational design of efficient hydrogen production catalysts.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"58 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306157","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, the functional failure of 3D-printed PDMS structures caused by insufficient interlayer bonding strength significantly limits their applications. To address this challenge, this study innovatively proposes a manufacturing method for selective PDMS curing based on photothermal conversion, in which polyimide (PI) film is introduced as an intermediate thermally conductive medium to enable selective laser heating and localized curing of highly transparent PDMS. This strategy not only provides structural support for functional layers via laser-selective curing of PDMS but also retains substantial uncured regions to enable covalent crosslinking between adjacent PDMS layers, thereby effectively improving the interlayer bonding strength. Moreover, the laser-cured zones are encapsulated within these uncured portions, further achieving the enhancement of interlayer bonding strength of PDMS-based 3D-printed devices. The results demonstrate that compared with conventional fully curing layer-by-layer printing approaches, the samples prepared by this strategy exhibited cohesive failure during the T-peel test, while pull-off testing demonstrated a minimum 2.36-fold enhancement in interfacial bonding strength, and optical microscopy observations at 20× magnification revealed no delamination at the interfaces. Leveraging this method, a flexible strain sensor with stable performance over 1,000 cycles and a microfluidic chip capable of withstanding a flow rate of 1000 μL/min without leakage were successfully fabricated.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"26 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145314753","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}

The results reveal that, despite the high static strength achieved in LPBF TWIP steels, their fatigue strength remains relatively low. The heat treatments improved fatigue resistance by relieving residual stresses and/or disrupting cellular structures, particularly under low stress amplitudes. A predictive H-parameter model was proposed by integrating defect size, location, circularity, along with a weighting factor (<em>h</em>), to evaluate fatigue life under various conditions. In the as-built condition, decreasing stress amplitude caused a transition in crack initiation modes from surface lack-of-fusion (LOF) defects to internal {111} slip planes governed by microstructural features. The latter involves the activation of multiple slip systems with maximum Schmid factors exceeding 0.4 along the crack path, driven by the inhibition of dislocation motion by cellular structures. This promotes strong interactions among nano-twins and stacking faults (SFs) within multiple active slip systems, leading to localized stress concentrations at these intersections and twin boundaries. In addition, both low-angle grain boundaries (LAGBs) and cellular structures may hinder intragranular crack propagation and contribute to crack deflection.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"4 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306158","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}

The global and local orientation configurations of soft-oriented DRXed grains (basal Schmid factor ˃ 0.3) were quantitatively assessed. A soft-surrounding-soft configuration facilitated early basal slip and enhanced ductility but led to pronounced plastic incompatibility and low yield strength (YS). A hard-surrounding-soft configuration increased but limited ductility due to poor slip transfer. In contrast, the B1 sample exhibited a (soft+hard)-surrounding-soft configuration that moderated stress gradients and enhanced crack resistance, achieving the best strength-ductility combination.

In the present work, superior synergistic combinations of ultrahigh strength (ultimate tensile strength, ∼2026 Mpa), desirable ductility (total elongation, ∼13%), and exceptional fracture toughness (<em>K</em>_JIC, ∼119 Mpa m^−1/2) were achieved in a low-carbon alloy transformed-induced plasticity (TRIP) steel by microstructural architecture, specifically, by utilizing multi-delamination crack toughening evolved from microvoids induced toughening and deformation-induced martensitic transformation (DIMT) toughening strategy. Firstly, nanoscale lamellar ferrite (<em>α</em>) and metastable austenite (<em>γ</em>) strengthened by high-density Cu-rich precipitations were obtained by warm rolling (WR). Fabricated numerous lamellar interfaces and surrounding ductile <em>α</em> and <em>γ</em> phases in the WR620 steel trigger a microvoids-induced toughening mechanism that is characterized by high-density non-aggregated microvoids (∼2.5 × 10⁴ mm⁻²), resulting in superior crack-initiation and crack-growth toughness. Secondly, maintaining these microstructure characteristics, further strengthening of constituent phases was achieved by cold rolling deformation at cryogenic temperature, which implants preferentially high-density dislocations in <em>γ</em> and ensures ultrahigh mechanical stability regarding DIMT in WR620-N2CR steel. Combined with ultrastrong <em>α</em>/<em>α</em>’, optimized TRIP-assisted lamellar microstructure conquers the dilemma of strength-ductility tradeoff at ultrahigh yield strengths, meanwhile, without significantly deteriorating fracture toughness. These fabricated lamellar interfaces serve as preferential sites for the initiation of delamination microcracks, resulting in excellent crack-initiation fracture toughness. Nanoscale lamellar constituent phases with ultrahigh strength and deformed <em>γ</em> with ultrahigh critical martensitic transformation stress further retard catastrophic propagation and coalescence of delamination microcracks, which demonstrates a multi-delamination crack toughening mechanism from the perspective of observed fractographic features and derived micro-mechanically ductile fracture model. Additionally, the <em>in</em>-<em>situ</em> DIMT toughening enhances fracture toughness by simultaneously absorbing energy, which determined contribution accounts for 28.0% and 21.3% of the total fracture toughness in WR620 and WR620-N2CR steels, respectively. To summarize, our findings provide a microstructural architecture strategy and reveal synergistic strengthening-toughening mechanisms to design steel with ultrahigh strength-ductility and superior damage-resistance synergy.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"75 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145306159","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 in this study, the synergistic effect of Ti and Fe elements optimized precipitation behavior and nanostructure design, thereby overcoming the inherent strength-plasticity and strength-conductivity trade-offs in Cu-Ti alloys. Trace Fe additions promote dispersed nucleation of nanoscale β'-Cu₄Ti precipitates, leading to a significantly higher density and finer size of the strengthening phase. Atom probe tomography analyses reveal that the Fe initially co-precipitates with the β'-Cu₄Ti phase, subsequently segregating from the core toward the growth tips. The enrichment of Fe atoms significantly raises the diffusion energy barrier for Ti within the β'-Cu₄Ti phase, thereby facilitating sufficient precipitation of residual Ti solutes. The precipitation of nanoscale spherical Fe₂Ti phases is attributed to their favorable heterogeneous nucleation at the interfaces of β'-Cu₄Ti precipitates. The formation of primary Ti₂FeCu and TiFe phases refines the grain size of Cu-3Ti-0.2Fe alloy from 127 to 7 μm, and further reaches 310 nm after processing. After thermomechanical treatment, we report a 1228 MPa strength Cu-Ti-Fe alloy with improved conductivity and elongation to 16.8 %IACS and 5.5%. The uniform nanocrystalline and the enhanced precipitation behavior of β'-Cu₄Ti phases contribute significantly to the comprehensive properties.

Finite element simulation and mechanical analysis indicated that the multi-point support structure, resembling a truss framework, formed in the oxidized wood template significantly improved the strength of TSP@Ca aerogel (9.99 MPa), with a 154.84% enhancement relative to that of oxidized delignified wood (TODW). The limiting oxygen index of TSP@Ca3 aerogel was as high as 43.3%, and it can extinguish immediately when the fire was removed. The introduction of PA and Ca²⁺ promoted the dehydration, cross-linking, and charring of TSP@Ca aerogel, while the produced phosphorus-containing free radicals played an inhibitory role in the gas phase. Therefore, the peak of heat release rate of TSP@Ca aerogel was 80.66% lower than that of TODW, showing excellent fire safety. Benefiting from the complex heat conduction path and enhanced interface resistance, the thermal conductivity of TSP@Ca was 46.4% lower than that of TODW.

Traditional insulation coating approaches to improving the high-frequency performance of SMCs have been limited by difficulties in controlling coating thickness, susceptibility to decomposition during heat treatment, and magnetic dilution effects caused by non-magnetic insulating materials. This study addresses these limitations by introducing a novel biomineralization-inspired strategy to coat FeSiAl powders with NiZn ferrite nanoparticles.

The resulting NiZn ferrite/FeSiAl composites, prepared via mechanical mixing, exhibited an heterogenous insulation coating that significantly enhanced magnetic domain wall mobility and electrical resistivity compared to uncoated FeSiAl SMCs. Consequently, the FeSiAl/NiZn (FSA-NZ) SMCs demonstrated enhanced relative permeability, a high domain-wall resonance frequency, and remarkably low high-frequency power loss (944.8 mW/cm³ at 1 MHz/50 mT).
