Then, the (WZrNbTaM)C (M=Cr, Ni, Ti) high-entropy carbide powders are synthesized by carbothermal reduction reaction. The synthesized high-entropy carbide powders are densified with addition of Co and Ni at a lower temperature. The phase analysis and microstructure observation, followed by mechanical property test, including Vickers hardness and fracture toughness of the high-entropy carbides are investigated. Finally, electrochemical corrosion behavior test of the samples is conducted in NaCl solution. It is found that a small amount of metal (2.5 wt.% Co and 2.5 wt.% Ni) can reduce the sintering temperature of high-entropy carbides, and the relative density can reach more than 96% at 1600 °C. The metal is uniformly dispersed among the high-entropy ceramic particles, facilitating liquid-phase mass transfer and pore elimination. (WZrNbTaNi)C-Co-Ni has the best comprehensive mechanical properties, with hardness and fracture toughness reaching 19.7 GPa and 6.6 MPa·m 1/2 , respectively. In 3.5 wt.% NaCl solution, oxides have formed on the surface of the samples after electrochemical corrosion test, and (WZrNbTaCr)C-Co-Ni shows excellent corrosion resistance.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"40 1","pages":"2660-2671"},"PeriodicalIF":0.0,"publicationDate":"2025-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Achieving effective dispersion and robust interfacial bonding between Gr and the ntCu matrix is critical to this process. In this study, Cu-Gr nanocomposites were prepared by using pulse co-electrodeposition (PCED). An optimized microstructure comprising a high density of nanotwins and homogeneously dispersed graphene was obtained at a graphene concentration ( C Gr ) of 0.1 g/L and a pulse current density of 300 mA/cm 2 . The Gr layers were incorporated preferably in the incoherent twin boundaries (ITBs), exhibiting an orientation relationship described as (10 1 ‾ 0) Gr //(11 1 ‾ ) Cu with the matrix. The Young's modulus of the Cu-Gr samples increases with increasing C Gr , with a maximum of ∼143 GPa for C Gr of 0.3 g/L, owing to the integration of graphene. The ntCu-Gr sample with C Gr of 0.1 g/L exhibits the highest hardness of ∼2.73 GPa, resulting from the synergistic strengthening effects of the nanotwins and graphene. Our study offers a pathway for the fabrication of ntCu-Gr nanocomposites with enhanced hardness by PCED and highlights the unique interfacial structure between nanotwins and graphene.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"5337-5345"},"PeriodicalIF":0.0,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Phenyl silicone rubber exhibits extraordinary thermal stability, radiation resistance and weather resistance, making it particularly suitable for use in the aviation and aerospace. However, its inherent flexibility and weak intermolecular interactions result in narrow damping temperature ranges and instability of the mechanical properties at extreme temperatures, which severely limits its practical application. In this study, we designed and synthesized five soluble diphenyl MQ resins with different M/Q ratios, and developed a novel dissolution blending method to incorporate resins as damping fillers into phenyl silicone rubber to prepare high-performance damping composites. The dissolution blending method enhances interface effect and facilitates more bound rubber between phenyl silicone rubber and diphenyl MQ resin, which promotes efficient stress transfer and energy dissipation. The results show that, when the M/Q ratio is 0.8, the dissolution blended damping composite (DBDC) possesses a significant improvement of 230.9 % in the effective damping (tan δ > 0.3) temperature range compared to the blank phenyl silicone rubber. Remarkably, the DBDC also exhibits exceptional mechanical performance and aging resistance, displaying tensile strengths above 5 MPa at both 150 °C and −50 °C, maintaining over 95 % of its original tensile strength and hardness after 96h aging at 150 °C. This work proposes a viable strategy for the preparation of high-performance damping composites suitable for extreme environments.","PeriodicalId":501120,"journal":{"name":"Journal of Materials Research and Technology","volume":"39 1","pages":"3520-3530"},"PeriodicalIF":0.0,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147333773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
