【 摘 要 】

Ti3SiC2/Al2O3 composites were prepared by vacuum hot pressing sintering at different temperature (1400 °C, 1450 °C and 1500 °C) ) under 30 MPa for 1.0 h, the effects of temperature on element diffusion and mechanical properties of Ti3SiC2/Al2O3composites were investigated. Temperature has a strong influence on the mechanical properties and interfacial element diffusion of materials that higher temperature is beneficial to the densification of Ti3SiC2/Al2O3composites to enhance the mechanical properties of it. The diffusion of Ti and Si occurs mainly at higher temperature accompanied by some decomposition of Ti3SiC2.
