ժҪ The L��ders deformation behavior in a medium Mn transformation-induced plasticity (TRIP) steel is investigated at different temperatures ranging from 25 to 300��C. It demonstrates that the L��ders band appears at all testing temperatures but with varied L��ders strains which do not change monotonically with temperature. The martensitic transformation is simultaneously observed within the L��ders band in varying degrees depending on the testing temperature. It is well verified that the martensitic transformation is not responsible for the formation of L��ders band, and a reasonable explanation is given for the non-monotonic variation of L��ders strain with increasing temperature.
