| Abstract: | By means of THERMECMASTOR-Z hot simulation testing machine, the experiments of hot simulation of 37Mn5 steel are carried out in order to investigate the influence of deformation temperature, deformation level and deformation rate on critical strain. The mathematical model of critical strain of 37Mn5 steel is constructed, and computer regressive analysis of the model finds that the result is of high identical degree. |
