Abstract
Attention focuses on the macroscopic localization of the plastic deformation and structure in polycrystals of low-carbon 08ps steel sheet after hot rolling as a result of electrolytic saturation by hydrogen in a thermostatic three-electrode cell at constant potential. The basic types of macroscopic localization of the plastic deformation and its parameters (the velocity and wavelength) at different stages of strain hardening are determined by two-position speckle photography. By optical and electronic microscopy, the influence of interstitial hydrogen atoms on the defect substructure and morphology of cementite is investigated. The formation of dislocational substructure is considered. Torsional flexure of the α-phase lattice is discovered, corresponding to flexural extinction contours. The basic sources of the stress fields are the boundaries of the grains and fragments.
