The features of plastic-deformation localization in the low-carbon steel plate (0.07% wt. C) on the yield plateau in the absence of strain hardening, at the stage of linear hardening with a constant coefficient of strain hardening, and at the stage of parabolic work hardening are discussed. Using the method of double-exposure speckle photography, the major types and parameters of plastic-flow localization at different stages of deformation hardening of steel in the three states (after hot rolling, pickling and descaling, and electrolytic hydrogen saturation with a three-electrode electrochemical cell at a constant controlled cathode potential of the hot-rolled samples) are identified.
Key words: plasticity, strength, speckle photography, localization of deformation, hydrogen embrittlement.
