摘要：
The results of investigations of the influence of hydrogen on the processes of phase formation in structural materials are analyzed. On the basis of the study of self-diffusion, interdiffusion, and atomic ordering in hydrogenated nickel and alloys of the Fe-Ni, Ni-Mo, and Ni-Mo-Re systems, it is shown that hydrogen accelerates these processes by increasing the degree of atomic ordering and decreasing the critical temperatures of formation and decomposition of intermetallic phases. By analyzing these alloys and VKh-4A steel taken as an example, we demonstrate the possibilities of application the obtained results to the improvement of the physicomechanical properties of these materials.
