Simulation and prediction of the development of dynamic recrystallization during the deformation of low-alloy low-carbon steel blanks

Resumo

The results of physical modeling of plastic forming using a torsional plastometer are used to analyze the effect of the temperature–deformation parameters on the development of dynamic recrystallization in a low-alloy low-carbon steel. A technique is proposed to predict the structure formation in zones with a heterogeneous state of stress, and it is based on the results of numerical simulation and physical modeling. This technique can be applied to optimize the process of plastic forming and the subsequent finishing treatment of complex-shape parts.
