The morphologies and types of silicides that developed on the surface of Inconel 738 alloy were examined using energy dispersive X-ray spectroscopy (EDS), scanning electron microscopy (SEM), and X-ray diffraction analysis (XR<b>D)</b>.

In nanoindentation tests, there was an increase in reduced elastic modulus from 212 to 241 GPa and in hardness from 6.7 to 16 GPa. A decrease of up to 84% was observed in the wear losses of siliconized Inconel 738 alloy at 950 °C–6 h due to the presence of silicide layer. Furthermore, the Taylor expansion model was utilized to assess silicon diffusivities within Ni silicide layers, incorporating the silicon diffusion coefficient within the Ni matrix.

In this study, we investigate the effects of bulk porosity and surface roughness of TPMS-based Gyroid structures fabricated via selective laser melting on various biocompatibility factors through quantitative linear regression analysis. The results demonstrate that bulk porosity and surface roughness influence biocompatibility parameters in distinct and complementary ways. Bulk porosity exhibited a strong correlation (R² &gt; 0.9) with osteogenesis-related factors, including osteoblastic cell activity, BMM, ALP-p, and OPG, indicating its critical role in promoting cell adhesion, proliferation, and early-stage osteogenesis. The high correlation with OPG suggests that bulk porosity contributes significantly to bone tissue stability and regeneration by fostering a conducive microenvironment. Conversely, resorption-related markers (RANKL) and late-stage osteogenesis markers (OCL) showed relatively low correlations with bulk porosity, indicating its primary influence on early osteogenesis processes. In contrast, surface roughness demonstrated strong correlations (R² &gt; 0.9) with resorption-related markers (RANKL) and late-stage osteogenesis markers (OCL). This highlights the importance of curved surface characteristics in modulating bone remodeling processes. The strong correlation with OCL (R² &gt; 0.98) underscores the role of surface roughness in regulating late-stage osteogenesis, while moderate correlations with ALP-p and OPG (0.38 &lt; R² &lt; 0.53) suggest a limited impact on early-stage osteogenesis. These findings reveal that bulk porosity and surface roughness play complementary roles in biocompatibility. Bulk porosity enhances osteogenesis and tissue stability by providing expanded surface area and optimized pore structures, whereas surface roughness directly influences bone resorption and late-stage cellular activity, particularly on curved surfaces.

Formability studies were conducted with varying spindle speeds. At higher forming speeds, the formability is greater compared to lower spindle speeds due to the presence of shear strains during incremental forming. The electron backscattered diffraction studies showed nearly 73% of reduction in grain size when the Nitinol foil was formed at highest spindle speed due to frictional heat and promotion of dynamic recrystallization. The Mechanical properties of Nitinol foil deformed with higher forming speeds (200 rpm) showed higher values of 995 MPa and 337 Hv when compared to its counter parts. Fracture behavior was investigated using the void coalescence method. The parameters for void coalescence, such as the void length-to-width (L/W) ratio, void size (µm), d-factor, and ligament thickness, were measured.

Post-fabrication, the FSP-Al6061 composite (FSP-AMC) underwent T6 heat treatment to re-precipitate the β′′ phase dissolved during FSP.

Therefore, this investigation explores the processing-structure-property correlation in AlSi10Mg using a realistic 3D microstructure-based crystal plasticity (CP) approach. The work hardening in AlSi10Mg has been explored based on two mechanisms: (i) load bearing by the Si-phase and (ii) dislocation-driven hardening. The strain incompatibility introduced by the harder Si-phase generates geometrically necessary dislocations, which influence the hardening behavior. The role of the slip system interaction based on the slip activity on all active slip planes was also explored in understanding the work hardening behavior. The transformation in silicon morphology after the heat-treatment changes the interaction of dominant slip systems, thus leading to higher work hardening in the as-built condition during tensile deformation. The result of this study predicts that the tailoring of the Al-Si cellular structure can help to achieve the desired mechanical properties in the additively manufactured AlSi10Mg.</p><h3>Graphic 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":"31 10","pages":"2855 - 2874"},"PeriodicalIF":4.0,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128602","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}

In this paper, SnSbCu11-6 alloy semi-solid slurry was prepared by ultrasonic vibration treatment (UVT) process. The effects of UVT termination temperature on microstructure size, distribution and properties were studied. The results show that UVT can significantly refine the SnSb phase and Cu₆Sn₅ phase and improve the distribution uniformity. The SnSb phase are tightly bound to the matrix α-Sn phase and exist semi-coherent interface matching in (111)_SnSb//(200)_α−Sn. On the contrary, the Cu₆Sn₅/α-Sn interface is clear and well-bonded but no orientation relationship exists. The average grain size of SnSb phase and the average length of Cu₆Sn₅ phase decreased first and then increased with the decrease of the termination temperature of UVT. The optimal termination temperature of the UVT is 260 ℃ near the precipitation temperature of SnSb phase, at which the average grain size of SnSb phase is 48.8 ± 8.8 μm and the average length of Cu₆Sn₅ phase is 10 ± 4.2 μm. The tensile strength and elongation are 70.3 MPa and 3.6%, respectively, which are 6.0% and 140% higher than that of liquid casting. It is likely attributed to the fine grain strengthening with the semi-coherent interface SnSb phase and microstructure homogenization. Moreover, the fracture mechanism indicates that the fine SnSb phase can effectively prevent crack propagation and significantly improve the plasticity of the alloy.
