Study of Localized Plastic Deformation of Hadfield Steel Single Crystals Using Speckle Photography Technique

Abstract

The evolution of local strain during stretching of high-manganese carbon austenite (Hadfield steel) was studied. The ordered patterns of strain localization proved to be closely related to the stages in the stress–strain curve. The results of this study are compared with analogous data for chromium–nickel nitrogen austenite single crystals. The velocity of self-consistent motion of the sites where plastic strain during stretching of gamma-Fe single crystals is nonuniform was determined as a function of the strain hardening coefficient and deformation mechanism.
