| Abstract | ||
| The kinetics of plastic flow localization in low carbon steel/stainless chromium-nickel steel (ASTM A414 grade A / AISI 304) composite under uniaxial tensile testing is studied via digital speckle image correlation method. The types and parameters of local deformation in the base and cladding layers of the composite are determined at different stages of work hardening. It is found that in the low carbon steel basal layer, the distribution of localized deformation at the yield plateau represents a single localized front similar to the Lüders band. In the austenitic steel coating layer, the distribution of localized deformation at the yield plateau represents localized fronts similar to the Portevin–Le Chatelier effect bands. | ||
