"The aim of this project is to determine the possible mechanisms of stress corrosion cracking (SCC) and intergranular corrosion (IGC) of stabilized and nonstabilized austenitic steels with emphasize on different conditions of their thermal stability. Theevaluation of the influence of the surface passivation conditions and heat affectation of grain boundaries on the local corrosive damage will be accomplished by the electrochemical measurements of the potentiodynamic polarization curves and by the usingof potentiokinetic reactivation method (EPR). The resistance of the titanium stabilized austenitic steel 08Ch18N10T and nonstabilized austenitic steel type 316L to the initiation of SCC and to IGC at elevated temperatures up to 280 \u00B0C will be observed inthe model medium of crevices, that simulates service conditions of the aqueous solution of power systems. From the results of the short-term electrochemical tests and long-term exposuring corrosive tests and their mutual comparison will be determined"@en . .
