Abstract
Titanium carbonitride (Ti(CN))-based cermets have been studied for applying them to cuffing tools and wear-resistant tools. Thermal shock resistance is an important property of tool materials used in severer thermal environment. However, evaluation method of thermal shock resistance has not been sufficiently established for cermets. In order to develop a method to evaluate the thermal shock resistance, irradiation experiments using a laser were conducted; laser beam was irradiated on the surface of thin specimens. The experimental results indicate that deformation of cermets by irradiation depends on the thermal properties, the mechanical properties and the plasticity of specimen. It is thought that the relationships between the deformation and the maximum temperature of cermets during irradiation characterize the material behavior under thermal shock environment.
