Significance of cold rolling reduction on Lüders band formation and mechanical behavior in cold-rolled intercritically annealed medium-Mn steel

We elucidate here the significance of cold rolling reduction on Lüders band formation and mechanical behavior in cold-rolled intercritically annealed medium-Mn steel. The study indicated that Lüders strain can be decreased by decreasing cold rolling reduction. Moreover, inactive recovery and recrystallization of ferrite consisting of a high dislocation density was responsible for the presence of low Lüders strain.
