The microstructure, mechanical and thermal properties, and molten silicate environment (CaO-MgO-Al₂O₃-SiO₂, CMAS) corrosion behavior of the ceramic were also investigated. The results show that the ceramic possesses excellent sintering resistance, with an average grain growth rate of 0.5 nm h⁻¹. In addition, the ceramic exhibits enhanced mechanical properties, with a hardness of 13.48±0.32 GPa and a fracture toughness of 1.79±0.04 MPa m^1/2. In terms of thermal performance, the ceramic exhibits low thermal conductivity (1.68 W m⁻¹ K⁻¹, 1000°C) and moderate thermal expansion coefficient (CTE, 10.78×10⁻⁶ K⁻¹, 1200°C). The CMAS corrosion experiment shows that the corrosion products are mainly composed of (RE, Ca)-ZrO₂ and apatite-type Ca₂RE₈(SiO₄)₆O₂ structures, in which the content of rare-earth elements is directly proportional to the optical basicity (OB) of its oxide, while it is exactly the opposite in (RE, Ca)-ZrO₂. In addition, the difference in OB is a key factor affecting the corrosion resistance of high-entropy rare-earth zirconates (HE-REZs), as HE-REZ composed of heavy rare-earth elements exhibit better corrosion resistance due to their lower OB value. This study provides a theoretical and experimental basis for the application of HE-REZs in high-temperature CMAS corrosion environments.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"18 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141161","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 solidification behavior in the Zn molten pool during the LPBF process under the influence of thermoelectric magnetic effects was simulated using a physical model that integrated SMF. The results indicated that the thermal electromagnetic force induced by SMF reached up to 10⁶ N/m³, effectively fragmenting regular Zn columnar dendrites and enhancing heterogeneous nucleation efficiency, thus promoting the columnar-to-equiaxed transition and grain refinement. Consequently, compared to samples printed without SMF assistance, the mechanical anisotropy index of yield strength and elongation in the SMF-assisted LPBF-printed Zn sample was significantly reduced from 18.63% and 16.49% to 2.46% and 2.58%, respectively, while maintaining superior strength-ductility synergy. This nearly isotropic mechanical behavior primarily resulted from well-modulated grain characteristics that served as a sustainable source of strength-ductility by coordinating grain boundary strengthening and dislocation strengthening mechanisms, as well as utilizing balanced basal &lt;<em>a</em>&gt; slip and pyramidal &lt;<em>c</em>+<em>a</em>&gt; slip deformation modes.

To tackle this issue, a dual-inorganic-rich artificial layer is engineered via the spontaneous reaction of PCl₅ with Na, resulting in a Na₃P- and NaCl-rich interphase on metallic Na (PCI-Na). In the dual-inorganic-rich interphase, NaCl featuring electronic insulation and a low diffusion barrier can effectively prevent continuous electrolyte decomposition and mitigate the formation of \"hot spots\" for Na deposition. In addition, Na₃P with high interfacial energy and good sodiophilicity helps suppress the dendrite formation and promote uniform sodium plating. As a result, symmetric cells of PCI-Na cycle for nearly 500 h at 1 mA cm⁻² and 2 mAh cm⁻², outlasting the bare sodium counterpart.

Superplastic Zn alloys are favorable for the forming of complex medical devices, however, superplastic alloys usually exhibit relatively low strength. In this work, the alloy design concept for biodegradable Zn is employed to break the trade-off between strength and ductility. Quasi-superplasticity was achieved in a high-strength Zn-2Cu-0.15Mg alloy with a bimodal grain structure (ultrafine and fine grains) through a combined process of hot extrusion and room-temperature (RT) rolling. RT tensile tests were subsequently conducted under various strain rates. Notably, the processed alloys demonstrated an outstanding combination of properties: a quasi-superplastic strain of approximately 138.2%, a yield strength (YS) of ∼219.5 MPa, and ultimate tensile strength (UTS) of ∼301.5 MPa at a strain rate of 1 × 10⁻⁴ s⁻¹. Using quasi-in-situ electron backscatter diffraction (EBSD) analyses, we systematically investigated the microstructure and texture evolution of the rolled alloy during quasi-superplastic deformation at different strains. The findings indicated that the ultrafine grains experienced grain rotation and grain boundary sliding (GBS), whereas dislocation creep was predominant in fine grains. Dynamic recrystallization (DRX) and GBS significantly contributed to the quasi-superplastic strain during tensile deformation. Additionally, numerous spherical submicron-sized CuZn₄ phases created abundant phase interfaces, which facilitate quasi-superplastic deformation through phase boundary sliding (PBS).","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"62 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145141521","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}

Inspired by the periodic arrangement of hard and soft zones in biological armors which can achieve load redistribution and impact dissipation, this work successfully constructed a biomimetic armor structure of multi-scale heterostructures (MSH) in Cu-2.9 wt.% Ti alloy sheets based on the localized electropulsing treatment (LEPT) technology. Room-temperature tensile testing combined with Digital Image Correlation (DIC) analysis revealed that the heterostructure reduces strain concentration during deformation. This results in a ∼64% enhancement in ductility compared to conventionally aged samples, with only a ∼14% reduction in strength, leading to a 36% increase in the strength-ductility product (UTS × EL). The retained extensive soft zones provide a foundation for good ductility, while the heterogeneous deformation-induced (HDI) strain hardening and HDI strengthening resulting from deformation incompatibility significantly enhance the alloy's strength, effectively suppress localized necking, and enable sustained, uniform deformation. This multi-scale heterostructure significantly enhances the strain hardening capacity of the material, not only providing a novel paradigm for designing high-strength, high-ductility alloys, but also offering theoretical basis and technical support for the flexible design and targeted regulation of heterostructured materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"18 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145153658","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}

KBs-containing samples exhibit exceptional mechanical synergy at room temperature, achieving a yield strength of 950 MPa, an ultimate tensile strength of 1.06 GPa, a uniform elongation of 9.5%, and a total elongation of 11.6%. Results indicate that this enhancement originates from complementary strengthening mechanisms of KBs-induced hetero-grain refinement and hetero-deformation-induced (HDI) hardening. Moreover, KBs-mediated crack deflection and grain boundary delamination effects preserve ductility. At elevated temperature (400°C), KBs maintain functional efficacy through persistent Hall-Petch strengthening and sustained HDI hardening despite significant grain boundary weakening. The suppression of boundary delamination arises fundamentally from reduced strain hardening differentials between grain clusters with high-density KBs and low-density KBs, mitigating intergranular crack initiation and propagation from interfacial strain incompatibility. Remarkably, KB-containing alloys exhibit superior creep resistance at 400°C and 500 MPa compared to their homogeneous counterparts. Creep deformation is primarily governed by screw dislocation glide, which results in a very low creep rate (4.3651 × 10⁻⁹ s⁻¹) and negligible creep strain, outperforming other cladding materials.","PeriodicalId":16154,"journal":{"name":"Journal of Materials Science & Technology","volume":"48 1","pages":""},"PeriodicalIF":10.9,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145127776","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}
