Abstract : The procedure for testing for thermal fatigue should provide the possibility for variation in the deformations within wide ranges, and the study of the conformity to law in thermal fatigue should be done with the separation of the influence of the thermal and mechanical factors. It was established that the individual features of the process of deformation do not have an influence in the formation of breakdown cracks. The breakdown from thermal fatigue under different stress states is described by the energy criterion. A relative evaluation of the resistance of materials to thermal fatigue can be done with the aid of approximation criteria.
