HYDROGEN SORPTION AND RADIOGENIC HELIUM IN STAINLESS STEEL 12Crl8Ni10Ti
The results of the investigation of kinetics of hydrogen sorption, accumulation and diffusion in steel 12Crl8NilOTi containing up to ~160 appm of 3He are described. It is shown that the presence of radiogenic helium results in formation of new states of hydrogen with high binding energy. The last results in increasing of the temperature of hydrogen release and appearance of peculiar features in release kinetics, such as appearance of very sharp peaks, which are characteristic for spontaneous breakup of the regions of hydrogen accumulation near facilitated paths of hydrogen liberation.
