Essay

Technical approaches to the study of influence of hydrogenation on physico-mechanical properties of the Fe- and Ni-based alloys doped with carbon have been developed. Competing influence of hydrogen and carbon on parameters of ferromagnetic transformation was revealed and it was shown that hydrogen decreases the temperature of Curie point, whereas carbon acts oppositely. The time and temperature regularities of this process in dependency on the structure state of the studied steel have been determined by studies of change in anomaly parameters of electrical resistivity to alternating current 10Х9ВФА. The heat treatment in hydrogen for atomic ordering has been found to impove the physical and strength properties of alloys in the Ni-W-Re system.
