Description

 The main idea of the work is to master the laboratory methods for the study of corrosion of solid-state materials, in particular reactor austenitic steel, in environments with oxygen. These corrosion processes during the work were investigated in the temperature range of 500 °С –700 °С. The object of the study is the processes of phase-structural transformations in customer-supplied samples of reactor austenitic steel in oxygen-containing environment and their influence on the mechanical characteristics of steel. The subject of the study is the physicochemical mechanisms of the structural-phase rearrangement in the samples of the reactor austenitic steel under different temperature effects in the conditions of oxidation, as well as the influence of the degree of oxidation on the mechanical properties of the material. The laboratory method of oxidation of samples of reactor austenitic steel in the environment containing oxygen under different thermal effects is implemented. The structural and phase characteristics of the materials before and after the tests were investigated. The results are proposed for practical use of the NSC «Kharkov Institute of Physics and Technology» of NAS of Ukraine.
