Abstract

The fracture resistance of a commercial TiB 2 particle/SiC matrix composite was evalu ated at temperatures ranging from 20 to 1400°C. A laser interferometric strain gage (LISG) was used to continuously monitor the crack mouth opening displacement (CMOD) of the chevron-notched and straight-notched, three-point bend specimens used. Crack growth resistance curves (R-curves) were determined from the load versus displacement curves and displacement calibrations. Fracture toughness, work-of-fracture, and R-curve levels were found to decrease with increasing temperature. Microstructure, fracture sur face, and oxidation coat were examined to explain the fracture behavior.
