Abstract
The present work is devoted to the study of the laws of macroscopic localization of plastic deformation of austenitic stainless steel AISI 321 at low and high temperatures. The studies of AISI 321 steel found that at the stages of linear strain hardening, the propagation velocity of the localized plastic deformation centers and the spatial period of local elongation change when test temperature increases by the exponential law. Patterns of plastic strain localization as single bands are due to the Portevin – Le Chatelier effect on jerky flow.
