Abstract
In this paper, the phenomenological approach which connects the recrystallization parameters with thermomechanical characteristics of deformation is implemented to simulation of structural transformations. Two cases were considered, when the growth rate of recrystallized volumes is damping fast, and when a weak growth of recrystallized grains is observed. A pattern of structural states was obtained among the models with fast decrease in growth rate of recrystallized grain and weak grain growth. The abatement of the sensibility to the intensity of grain growth with increasing of strain rate was established. The function of recrystallized volume has oscillating behaviour depending on time and coefficient of recrystallization intensity. These results were confirmed by experimental researches of rheological behaviour of steels at low strain rates and high temperatures.
