The regularities of non-uniform plastic deformation evolving on the Lüders bands are studied in a low carbon steel – austenite stainless steel bimetal via a digital image speckle method. The local strain distributions in the bimetal low-carbon steel base layer at the yield point stage are presented by the two strain localization bands that are similar to the Lüders bands. Analogous distributions arise at the yield point from the bimetal austenite stainless steel clad layer in the form of two strain localization fronts that are identical to the Portevin-Le Chatelier bands. Finally, the generation of strain localization bands is described in the context of a solid-state wedging model.
