Fracture Behavior of SiC-TiB₂ Composite Measured by Different Test Methods

Abstract:

SiC-TiB₂composite was prepared by boron (B) and carbon(C) as sintering additive via presureless sintering in 2180°C. Fracture toughness of SiC-TiB₂ measured by indentation method and single edge notched beam specimen tenichques were analyzed and compared, and the most suitable indentation method equation was confirmed. Results revealed that the fracture toughness and flexure strength of the materials were influenced at varied degree by the content of TiB₂, which had no effect on the selection of the most suitable equation for calculating the fracture toughness of the materials by indentation method. The fracture toughness decreases with the increasing TiB₂ content. When the TiB₂ content was 30%, SiC-TiB₂ composite had the best fracture toughness.
