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