Abstract
The paper presents the localization of the plastic deformation features. The studies were performed for the test samples 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. Enhancement of the localization of plastic deformation was established. Analysis of the stages of the stress-strain curves revealed the yield line, linear work-hardening stage and (Taylor) parabolic work-hardening stage. Using the speckle-photography technique, the patterns of plastic deformation localization were exposed with subsequent determination of the displacement vector fi eld in the fl at sample and calculation of the components of the tensor plastic distortion (local elongation εxx , εxy shift and rotation ωz ). The main type and parameters of the localization of plastic fl ow for distinct work-hardening stages were determined
