Description

CEA develops new austenitic and ODS alloys to limit the swelling and withstand very high doses. In this study, 10 Austenitic Stainless Steels with different content of phosphorus, nickel, silicon, titanium and niobium were elaborated and irradiated with iron ions at 600°C in several metallurgical conditions. Different effects on void swelling were observed by Transmission Electron Microscopy (TEM). The presence of dislocations, nano-precipitates and solutes in the matrix modify the size and the density of the cavities which appear during the irradiation. Results help to design new alloys optimized regarding the swelling resistance.
