Uniaxial Strength and Mode I Fracture Toughness of Hot Pressed Silicon Carbide (SiC) Materials.

Abstract

Silicon carbide (SiC) ceramics are being used and considered for a number of room temperature wear and optical applications where strength and fracture toughness are critical design parameters. Thus, there is a requirement for high-quality tensile strength and Weibull data for this class of materials. This report will present room temperature uniaxial tensile strength data, single-edge precracked beam (SEPB) fracture toughness (K sub IC) data, and fractographic analysis for several hot-pressed (HP) SiC ceramics. Strength and K sub IC data will be related to the microstructure and flaw population of the HP SiC materials studied.
