In the study of the evolution of deuterium atoms profiles of distribution in steels on depth after implantation or post-implantation annealing in the temperature range 300 ... 1500 K were used helium ions with an energy of 0.3 MeV and 1.4 MeV. The implantation of deuterium and helium ions with energies 15 and 30 keV, respectively, in a wide range of doses was carried out at room temperature and elevated temperatures. The dependence of the number of deuterium atoms trapped on the annealing temperature was determined. It has been found that the retention of deuterium in steels is greatly enhanced in the presence of radiation damage that occurs during irradiation of materials by accelerated argon ions - the temperature range of hydrogen release from the crystal lattice is shifted on 200 K to higher temperatures.The data of the evolution of the microstructure and defect accumulation levels and temperature ranges of gas atoms impurities holding in the austenitic and ferritic-martensitic steels, the thermodynamic parameters of the system "metal-helium" and "metal-hydrogen" were determined. It was found that the main factor of the helium retention is its binding energy with defects, not their concentration. It is shown that the retention of deuterium after implantation at room temperature to ferritic-martensitic steel is three times smaller than in austenitic steels at levels damage ~ 1 dpa. At elevated temperatures, deuterium irradiation capture efficiency decreases by two orders of magnitude. It is found a significant holding of hydrogen in the traps associated with gel bubbles and voids, which confirms the data obtained for stainless steels irradiated in a light water reactor.
