Following LSP and subsequent vacuum diffusion treatments, a reaction layer comprising five distinct zones with varying thicknesses formed: residual Ni, Ni solid solution, Ni₃Ti, NiTi, and NiTi₂. Beyond the NiTi₂ layer towards the Ti substrate, three characteristic regions were identified: flake distribution, mesh distribution, and substrate. Crucially, LSP significantly enhanced the interdiffusion of elements. The diffusion distance of Ni was greater in β-Ti than in α-Ti, with Ni content in β-Ti exhibiting a characteristic rapid-slow-rapid-slow decreasing trend. Notably, LSP promoted the diffusion of Ni into both α-Ti and β-Ti, and critically, also accelerated the diffusion of Ti towards the Ni side. This enhanced bidirectional diffusion resulted in increased growth rates and thicknesses of the NiTi and NiTi₂ layers. With the increase of laser power, the diffusion coefficient of Ni in β-Ti also increases and the diffusion coefficient is in 10^− 13 m²s^− 1 level. The promotion of interdiffusion by LSP is attributed to the introduction of lattice distortion, elevated dislocation density, grain refinement, and residual compressive stress at the interface. These findings provide significant insights for enhancing the performance of Ti-6Al-4V/Ni coatings in demanding applications and contribute to the design of more durable and efficient material systems for aerospace and automotive industries.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"32 4","pages":"1338 - 1354"},"PeriodicalIF":4.0,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147579311","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}

By introducing an H₂ – Ar mixed gas through a submerged lance, the deoxidation reaction occurs at the reaction interface during the rise of gas bubbles. Experiments were conducted at 1473 K, with a total gas flow rate of 0.5 × 10⁻⁵ to 1.5 × 10⁻⁵ m³·s⁻¹ and an initial H₂ partial pressure of 0.2 to 1.0 atm. The deoxidation rate equation of Cu melt was derived based on the two-film model, considering the mass transfer of dissolved oxygen (O) through the liquid boundary layer and the counter-diffusion of H₂ and H₂O through the gas boundary layer. Additionally, the change in the mass transfer resistances under different reaction conditions was analyzed to investigate the transition of the rate-controlling step. The derived model for the Cu deoxidation rate was validated against the experimental results and showed good agreement. The rate-controlling step successively changed from mass transfer in the gas boundary layer of H₂ to mixed-rate control phase and finally to a mass transfer of O in the liquid boundary layer. Under the conditions used in this study, a lower H₂ partial pressure increased deoxidation efficiency in the latter stage by promoting more complete H₂ consumption within individual bubbles.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"32 5","pages":"1687 - 1699"},"PeriodicalIF":4.0,"publicationDate":"2025-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667747","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 results showed that the microstructure of Nb–16Si–22Ti–3Al alloy without TaB₂ was mainly composed of Nbss phase, Nbss/Nb₃Si eutectic and a small amount of α-Nb₅Si₃ phase. With the TaB₂ addtion increased, the Nbss/Nb₃Si eutectic in the alloy gradually diminished and Nbss + (α,γ)-Nb₅Si₃ eutectic structure were found. Compared to the untreated condition, when 0.25 at% TaB₂ was added, the Nbss content in the alloy sample increased from 50.2 to 56.2 vol%, the Nb₃Si content decreased from 36.7 to 14.2 vol%, the α-Nb₅Si₃ content rose from 12.1 to 23.7 vol%, and the γ-Nb₅Si₃ phase emerged (5.2 vol%). The average fracture toughness of 0.25 at% TaB₂ alloy was the best among all samples, reaching up to 13.1 MPa·m^1/2.

This study investigates the effects of energy density on the damping behavior of laser powder bed fusion (LPBF) fabricated NiTi alloys by analyzing the evolution of microstructure and phase transformation behavior. As energy density increases from 72.7 to 240.0 J/mm³, relative density decreases from 99.55 to 98.67% due to the transformation of small spherical gas pores (~ 35 μm) into larger irregular keyhole pores (&gt; 100 μm), which increases the overall pore volume. Meanwhile, the martensitic transformation finish temperature (<i>M</i>_f) temperature increases from − 41 °C to 40 °C with energy density increases from 72.7 to 240.0 J/mm³, resulting in an increase in martensite fraction until the sample transformed into a full martensite state at room temperature. Internal friction (IF) at room temperature initially increases from 0.034 to 0.057 as energy density increases to 171.4 J/mm³ and then decreases to 0.050 at 240.0 J/mm³. This variation arises from the synergistic effects between pore defects and martensitic fraction. The highest internal friction (IF = 0.057, at a strain amplitude of 0.1% and frequency of 1 Hz) is observed at 171.4 J/mm³, corresponding to a high martensitic fraction and numerous fine pores.

The results demonstrate that increasing the Fe content progressively transforms the phase structure of the Fe_xCrMnAlCu HEAs from an initial BCC + BCC2(L2₁) configuration to an FCC + BCC structure. Microstructural analysis revealed that the dendritic regions primarily consist of Cr, Fe, Mn, and Al-enriched solid solutions, while the interdendritic regions comprise Cu and Al-enriched solid solutions. The addition of Fe promotes the formation of the FCC phase while simultaneously inhibiting the precipitation of the L2₁ phase. Immersion corrosion tests and electrochemical measurements indicate that the corrosion resistance of the Fe_xCrMnAlCu HEAs exhibits a graded degradation with increasing Fe content (Fe₀ &gt; Fe_0.5 &gt; Fe_1.0 &gt; Fe_1.5 &gt; Fe_2.0). The Fe₀ alloy demonstrated the optimal corrosion resistance, characterized by the highest corrosion potential and the lowest corrosion current density. This superior performance is attributed to its unique BCC + BCC2(L2₁) dual-phase structure and the formation of a stable, compact passive film during corrosion. In contrast, the Fe_0.5 alloy failed to develop a dense and stable passive film. Localized corrosion pits were observed on the dendritic regions of the Fe_1.0 alloy, while the Fe_1.5 and Fe₂.₀ alloys underwent severe selective dissolution of the dendritic phase. The deterioration in corrosion performance primarily stems from the synergistic effects of: (i) alterations in passive film characteristics induced by Fe addition, (ii) enhanced microgalvanic coupling resulting from the phase transition (BCC + L2₁ → FCC + BCC), and (iii) dilution of the critical corrosion-resistant element Cr, which significantly weakens the passivation capability of the dendritic regions.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":703,"journal":{"name":"Metals and Materials International","volume":"32 5","pages":"1572 - 1590"},"PeriodicalIF":4.0,"publicationDate":"2025-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667748","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}
