Paper Abstract

The influence of thermal cycles (heating up to 453 K, cooling to 123 K) on the change of the elementary compositionof surface layers of 12Kh18H10T steel and VT-1-0 alloy was studied on the samples of these materials in the LAS-2000 chamber (Riber, France). Decomposition of the higher oxides of iron, nickel, formation of lower oxides were found, as well as migration of O, C, Cl, N along the grain boundaries and formation of their chemical compounds which influence the materials destruction.
