Abstract
The paper considers factors influencing the change in hydrogen concentration in forgings made of medium-alloy steels. The computational modeling of the kinetics of changes in the hydrogen content under various variants of preliminary heat treatment is performed. It is shown that it is possible to achieve maximum completeness of hydrogen removal during diffusion processes of austenite transformation under isothermal conditions at the accumulation stage and during direct isothermal annealing (taking into account the increase in the diffusion coefficient of hydrogen in the γ- and α-phases by several orders of magnitude).
