Abstract
Thermal shock resistance of cermets was tried to evaluate by the infrared radiation heating method that a thin circular disk is heated and fractured by infrared ray concentrated on the central area with a constant heat flux. Thermal shock fracture toughness R2c could be measured for specimens with an edge notch, while thermal shock strength R1c could not for the specimens without the notch. It was thought, however, that R2c might depend on radius of curvature of the edge notch. Using the data of R2c, thermal shock strength R1c was calculated from the consideration of stress concentration. As a result, it was considered that thermal shock strength R1c could be applied to evaluation of thermal shock resistance of cermet and thermal shock resistance of Ti(C, N)-Mo2C-Ni cermets increased with an increase in the content of nitrogen and Ni.
