The article discusses the features of structure formation during thermal
cycling treatment of hypo eutectoid structural steels 20, 40X and 65G. The process of
thermal cycling treatment with heating without phase recrystallization and with complete
phase recrystallization has been studied. Thermal cyclic treatment without phase
recrystallization forms residual thermal stresses, causing an increase in the density of
dislocations, the development of the initial stages of recrystallization. The maximum
level of residual stresses is formed after 5 cycles. Thermal cyclic treatment with
complete phase recrystallization leads to the development of recrystallization processes
of varying intensity on the surface in the core of the steel sample. After 4 cycles, a
collective recrystallization is possible on the surface with obtaining a grain size
difference. In the core, the processes of polygonization and “recrystallization in place”
take place.
