We study the acoustic properties of inhomogeneous plastically deformed specimens made of 09G2S steel. The specimens with residual strains were successively subjected to heat treatment and hydrogenation from the gas phase. After each procedure, we measured the space distributions of the velocity of longitudinal acoustic waves. We also analyzed the mechanisms of changes in the velocity in the course of hydrogenation in the region of the specimen with residual strains.
