In this paper, the optimization of process parameters and the flash formation mechanism in inertia friction welding of 430/316L stainless steel were systematically studied. Using response surface methodology, this study determined the influence degree of welding parameters on the tensile strength of the joint, in descending order: friction speed, forging speed, forging pressure, and friction pressure. Under the optimized process parameters (friction speed 2750 r/min, friction pressure 4 MPa, forging speed 1350 r/min, forging pressure 7 MPa), the tensile strength of the welded joint was 520.5 MPa. Based on the thermal–mechanical coupling simulation and high-speed photography experiment, the dynamic formation mechanism of the flash under the synergistic effect of the welding interface temperature field, stress field, and plastic flow field was systematically revealed: High interface temperature leads to metal softening, the high stress at the edge and the low stress in the middle drove the plastic metal flow, the axial velocity gradient (5.28 mm/s at the top and 1.95 mm/s at the root) caused the flash to curl upward, and the radial inward flow (− 3.61 mm/s) intensified its bending toward the base metal side. The elucidation of this mechanism provided a direct theoretical basis for the active regulation of flash shape.</p></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 23","pages":"16871 - 16889"},"PeriodicalIF":3.9,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147828532","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As compared with ferrite (<i>δ</i>), the grain aspect ratio (GAR) of austenite (<i>γ</i>) exhibits more significant change, and the dislocation density in <i>γ</i> phase presents faster growth after cold rolling. Besides, the dislocation character in <i>γ</i> phase undergoes more profound transformations from screw type to edge type simultaneously. The change of dislocation character could facilitate the dislocation accumulation behavior at grain boundary (GB) in terms of their tendentious interaction with crystal defects. The changes above indicate that the <i>γ</i> phase suffers from more severe plastic deformation during cold rolling compared with that of <i>δ</i>. More pronounced work hardening behavior and more intense interaction between dislocation and GB have occurred in <i>γ</i> phase. The application of cold rolling significantly improves the yield strength from 302.53 MPa to 1113.29 MPa, and the ultimate tensile strength from 679.41 MPa to 1145.85 MPa, corresponding to an increase of 267.99% and 68.65%, respectively. Quantitative analysis on work hardening in <i>γ</i> phase in terms of macroscopic scale was carried out. The results show that the strain-hardening exponent of the <i>γ</i> phase (0.51) is significantly higher than that of the <i>δ</i> phase (0.39) and the growth rate of dislocation strengthening contribution is 45.62% and 21.09% for <i>γ</i> and <i>δ</i> phase, respectively, which further indicates that more intense hardening behavior has occurred in <i>γ</i> phase. More complicated interaction on dislocation activity and slip transfer between individual grains are discussed in terms of the geometrical compatibility factor <i>m</i>′. The lower <i>m</i>′ at <i>δ</i>/<i>γ</i> GB results in back stress generation and suppressed dislocation activity at grain boundary, while the larger <i>m</i>′ indicates easily slip transfer and exerts less inhibition on the dislocation motion. The back stress generation at GB is responsible for work hardening during cold rolling and results in enhanced yield strength.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 23","pages":"16715 - 16737"},"PeriodicalIF":3.9,"publicationDate":"2026-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147828561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The core–shell microparticles (Ti-3wt% Cu) were sintered using a high-heating-rate vacuum furnace and compared to samples prepared from conventional blended Ti-3wt% Cu and pure Ti powders. Microstructural characterization demonstrated that the core–shell approach produces Ti–Cu materials with higher density, lower porosity, and a more uniform copper distribution, surpassing the blended elemental approach. This structural uniformity and improved alloying correlate directly with enhanced mechanical properties, as evidenced by nanoindentation, which shows increased hardness and Young’s modulus. The superior mechanical performance is attributed to a combination of factors, including solid-solution strengthening by copper and the formation of the Ti–Cu intermetallic phases. The electrochemical behavior was assessed through potentiodynamic polarization and electrochemical impedance spectroscopy in simulated body fluid. Our results show that key parameters for corrosion assessment, including the corrosion current, breakdown potential, and polarization resistance, were similar to the control samples, indicating that titanium-copper alloys did not exhibit accelerated corrosion under the tested conditions.

This study investigates the microstructural evolution and corrosion behavior of 304L stainless steel fabricated by laser cladding to form a heterostructured \"sandwich\" (HS sample) and a bulk additively manufactured (AM) sample. The results indicate that the laser-clad samples exhibited inferior pitting resistance compared to the rolled and annealed 304L substrate in a 3.5 wt.% NaCl solution, with the AM sample performing the worst. This degradation is primarily attributed to micro-segregation-induced Cr-depleted zones and an unfavorable grain boundary character distribution, specifically a significant reduction in Σ3 twin boundaries and a high fraction of low-angle grain boundaries, which facilitated pit initiation and propagation. Interestingly, the ultra-fine grained (UFG) zone in the HS sample, despite its lower Σ3 fraction, showed relatively improved passivation behavior compared with the AM sample. This behavior is likely associated with its finer and more homogeneous microstructure and the high density of grain boundaries, which may facilitate short-range Cr transport and local repassivation.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":645,"journal":{"name":"Journal of Materials Science","volume":"61 23","pages":"16810 - 16831"},"PeriodicalIF":3.9,"publicationDate":"2026-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147828627","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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 rapid recombination rate of photogenerated electron–hole pairs in TiO₂ limits the potential to catalyze H₂ photogeneration. In this study, we rationally designed nickel/nickel selenide@nitrogen-doped carbon/TiO₂ (Ni/NiSe_x@NC/TiO₂) heterostructures via impregnation assisted by ultrasonication to enhance the photocatalytic activity of TiO₂ in H₂ production. This strategy yields a high interfacial contact between TiO₂ and Ni/NiSe_x@NC, which reduces the band gap energy and enhances the surface area. This combination yields a type-II heterojunction, as evidenced by X-ray photoelectron spectroscopy analysis of used Ni/NiSe_x@NC/TiO₂ and OH radical trapping via fluorescence analysis, with high conductive features due to the presence of NC. The presence of Ni metal provides additional sites for H₂ photogeneration. Such features significantly enhance the transfer and separation of electrons, as evidenced by a series of electrochemical analyses. Consequently, the photocatalytic H₂ generation of Ni/NiSe_x@NC/TiO₂ nanocomposites is enhanced compared with TiO₂, NiSe/TiO₂, and Ni/NiSe_x@NC. Moreover, the highest H₂ production rate is achieved by incorporating 3 wt% Ni/NiSe_x@NC on TiO₂ with the highest H₂ rate of 5985 μmol·g⁻¹. Different sacrificial agents show that glycerol exhibits the highest photocatalytic H₂ production rate compared to methanol and glucose. More importantly, Ni/NiSe_x@NC/TiO₂ shows good stability test until four cycles of photocatalytic reaction.
