Аннотация
This work determines the values of the deformation threshold necessary for the initiation and development of dynamic recrystallization within the investigated deformation temperature and strain rate for high-strength corrosion-resistant nitrogen-containing austenitic 04Kh20N6G11M2AFB steel. Analysis of diagrams shows that the deformation resistance increases with the decrease in the deformation temperature. A faint peak is observed at 1000–1200°C; it indicates the start of dynamic recrystallization. The structure of high-strength corrosion-resistant nitrogen-containing austenitic 04Kh20N6G11M2AFB steel after hot deformation with the strain rate of 0.1, 1.0, and 10 s–1 within the temperature range of 900–1200°С is studied by the EBSD analysis and transmission electron microscopy.
