The microstructure and properties of medium-carbon steel (0.45% C) are studied after torsional severe plastic deformation (SPD) at a high quasi-hydrostatic pressure and elevated temperatures of from 300 to 450°C. The initial treatment prior to the SPD is hardening for martensite. Analysis of the results shows that the SPD is effective for raising the characteristics of strength and microhardness at satisfactory ductility.
