【 摘 要 】

The results of studying of implanted hydrogen (deuterium) capture in austenitic steel Kh16N15M3T1 are reported. The peculiarities and possibilities of using the nuclear reactions method for measuring deuterium capture are discussed. The traps of implanted atoms and their capture by the elements of steel structure under radiation damage are considered. It is shown that the segregation intensity depends on the initial structure of the samples. A method is proposed for separating the contribution from different types of traps - structure elements - to implanted deuterium capture in irradiated volume. The mechanism of formation and evolution of radiation-induced segregation is discussed.
