description: This work is devoted to the study of dynamic recrystallization during hot deformation by physical modeling of the multi-pass hot rolling process. During the research, the following tasks were solved: 1. The analysis of up-to-date information on stainless steels and restoration processes during hot deformation is carried out. 2. As a result of physical modeling of the austenitic stainless steel multi-pass hot rolling process, stress-strain curves were obtained and the change in flow stress depending on the number of passes was analyzed. 3. The study of the microstructure of steel and its change depending on the number of passes by optical and transmission electron microscopy was carried out. Based on the results obtained, a conclusion about the effect of fractional deformation on the flow stress and the microstructure evolution of the steel is drawn. It is established that as the number of passes increases, the flow stress increases with an increase in the total deformation. The structure analysis showed that the recrystallization processes begin to develop only after the eighth pass.
