Conclusions
-
1.
The hot deformation of corrosion-resistant steels of the ferritic, austenitic, and austenitic—ferritic classes in the 900–1100°C interval at rates\(\dot \varepsilon = 10^{ - 2} - 10^{ - 3} \) sec−1 results in dynamic recrystallization.
-
2.
Various types of substructures are formed in the initial stages of plastic flow, depending on the deformation conditions and the type of crystal lattice of the steels, and, consequently, different mechanisms of dynamic recrystallization are realized.
-
3.
Substructure formation in the initial grains and gradual transformation of low- to high-angle boundaries are the mechanisms responsible for the formation of recrystallized grains in the ferritic steels over the entire temperature region investigated, and in the austenitic-class steel at high temperatures.
