Stabilita deformované vrstvy na povrchu ocelí exponovaných zvýšeným teplotám

Abstract

The thesis is focused on creep-resistant austenitic steels and some factors, which can influence their oxidation resistance in high temperature steam. Thesis consists of two parts, theoretical and experimental. Theoretical part describes basic methods of creep- resistance evaluation and properties of austenitic steels with stress on their oxidation behaviour. In experimental part are conducted tests on three austenitic steels, which are commonly used for components used in presence of water vapor at high temperatures. Influence of heat affection on their microstructure and corrosion resistance is examined.
