Abstract

Using the methods of ion implantation, electron microscopy and nuclear reactions the data on defect microstructure evolution, accumulation levels and temperature ranges of retention of hydrogen isotope - deuterium in austenitic steel SS316 have been obtained. Implantation of 15 keV deuterium ions to a dose of 1×1016 cm-2, 30 keV helium ions to a dose of 5×1016 cm-2, as well as steel irradiation with 1.4 MeV argon ions to a dose of 1×1017 cm-2 were carried out at room and elevated temperatures. The formation of dislocation structure, vacancy and gas-filled pores, and the nature of their size distribution were studied. The dependence of amount of trapped deuterium atoms on the defect structure evolution during annealing has been established. A considerable content of hydrogen in the traps associated with helium and argon bubbles was found, that confirms the data obtained for stainless steels irradiated in a light water reactors.
