Effects of Production Process on the Microstructure and Mechanical Properties of 65Mn Cold-rolled Strip
QI Weiwei
Abstract：The microstructure of 65Mn cold-rolled hardened and annealed strips and mechanical properties of annealed strips in different production process are studied. The main deformation form of pearlite is bending deformation when the raw material of unannealed 65Mn is cold rolled. Along with the increasing of total deformation rate, the pearlite bending deformation decreases and pearlite lamellar refinement becomes the main deformation form. The main deformation form of pearlite is lamellar refinement when the raw material of annealed 65Mn is cold rolled. Annealed 65Mn strips produced by the process of cold-rolling after raw materials annealed have uniform microstructure,steady mechanical property and preferable plasticity.
