Abstract: Two-dimensional rigid-plastic finite element method (FEM) was used for simulation of the effect of process parameters on the static recrystallization of 60SiMnA spring steel using MARC/AutoForge 3.1 software. A thermo-mechanical coupled analysis was conducted considering the heat transfer between the workpiece, the roll and the environment, and the heat generation due to plastic work. The static recrystallization laws under different processing conditions and the predicted distribution of the static recrystallization volume fraction on the deformation cross section are presented.
