Microstructures and Mechanical Properties of SiC-TiB2 Composite Prepared by Pressureless Sintering

摘要：

　　SiC-TiB2 composite was prepared at 2298 K by using pressureless sintering.The microstructures and mechanical properties of the SiC-TiB2 composite were investigated.The SiC-TiB2 composite with 5 mass % B4C-C showed the optimized comprehensive properties.The volume density,hardness,flexural strength and fracture toughness of that were 3.43 g/cm3,18.5 GPa,353 MPa and 4.67 MPa·m1/2,respectively.The excessive B4C-C content might decrease the mechanical properties of the composite.
