Thermal shock behavior of cermets and cemented carbides was studied in detail by using unnotched smooth bar specimens. Thermal shock was applied to the specimens by plunging them into a water bath at 290 K. After thermal shock experiments, bending strength, micro-Vickers hardness and fracture toughness of the specimens were investigated. As a result, two different types of thermal shock behavior were observed between cermets and cemented carbides. This difference indicates that microcracks occur more easily in cemented carbides than in cermets during thermal shock experiments.
