The effect of high-temperature cyclic loads on thermal stability, structure and microscopic chemical heterogeneity of deposited metal of the type of heat-resistant die steels was investigated. It was shown that, despite the fact that no diffusion of main alloying elements was detected during the tests, structure of the deposited metal experienced changes leading to its weakening.
