Repeated thermal shock tests were performed on cemented carbides to illustrate the advantages of the new method, which enabled us to esimate the intrinsic cyclic fatigue crack propagation behavior during repeated thermal shock tests and thermal fracture toughness values. It was shown that cyclic thermal fatigue crack propagation behavior and fracture toughness values were independent of the specimen height and cooling media of two different viscosities employed.
