【Abstract】 The compression test of 20CrMnTi steel with different carbon content by carburizing treatment was carried out by means of Gleeble-1500 thermo-mechanical simulator. The influence of forming temperature on flow characteristics of carburized 20CrMnTi steel was analyzed. Considering the characteristics of phase transformation for Fe-C-Cr-Mn alloy, the basic rule of the flow characteristics of carburized case and center of the parts was obtained.更多还原
