| Summary: | Заглавие с титульного экрана The microstructure and microhardness of high-nitrogen austenitic steel Fe-18Cr-23Mn-2,7V-0,2C-0,7N (in wt. %) after upset and high-pressure torsion (HPT) (6GPa) for 1/4, 1/2, and 1 revolutions at room temperature have been investigated. As the result of severe plastic deformation, steel microhardness increases by 1.5 times after HPT. Slip, twinning, formation of localized deformation microbands, γ-ε-phase transformation, and precipitation hardening are the main deformation mechanisms under HPT. At the same time, the level of solid solution hardening of steel remains high after deformation. |
