It is shown that at negative and room temperatures plastic deformation leads to curvature and fragmentation of martensitic lamellae, formation of new low-angle boundaries and a significant increase in the dislocations density. Deformation at high temperature contributes to the dynamic recovery, dynamic polygonization and increased sizes of carbide and carbonitride particles (M23C6 and MX type) UR - http://vital.lib.tsu.ru/vital/access/manager/Repository/koha:000925385 ER -
