| Abstract: | Hot forming mechanism of 35CrMo steel is studied in this paper through thermodynamics simulation experiment and data processing of 35CrMo steel. Effects of some variable parameters such as deforming temperature and strain rate on stress-strain relationship and recrystallization characteristics of 35CrMo steel are discussed. A material model of hot forming of this type of steel is established, which provides basic data for hot forming process of FEM numerical simulation and the scientific basis for rational determination of mechanics parameter and temperature parameter. |
