Abstract
This article presents the results of studying the structure of high-strength corrosion-resistant austenitic nitrogen-containing steel formed as a result of hot deformation. It was found that, depending on the temperature, degree and rate of deformation, the mechanism of formation of nuclei of dynamic recrystallization changes. At temperatures above 1100°C, nuclei are formed due to bending and subsequent migration of grain boundaries; however, with a decrease in temperature and an increase in the degree and rate of deformation, subgrains become centers of recrystallization near the initial boundaries.
