FORMATION OF STRUCTURE-PHASE STATES AND DISLOCATION SUBSTRUCTURES DURING THERMOMECHANICAL HARDENING OF Fe–0.09C–2Mn–1Si STEEL

摘要

Results of investigations of the structure-phase state and dislocation substructure formation during thermomechanical hardening of Fe–0.09C–2Mn–1Si steel in different regimes are presented. Methods of transmission electron microscopy reveal the formation of gradient states characterized by regular changes of the structure, phase composition, types, and parameters of the dislocation substructures over the structure cross section.
