Abstract—

A model is proposed for describing the behavior of the average size of austenitic grains and the dislocation structure of low-alloyed steels in the course of and after a hot deformation. The model takes into consideration the processes of recovery, dynamic recrystallization of grains, and the normal grain growth, as well as the strain-induced precipitation of carbonitride phases and their evolution. The calculation results are compared with the experimental data available in the literature and their satisfactory agreement is shown.
