Abstract

The possibility of producing an ultrafine-grained (UFG) structure in martensitic grade steels by severe plastic deformation (SPD) is investigated. The possibility of producing integral bulk billets with a UFG structure by high-pressure torsion and equal-channel angular pressing (ECAP) is demonstrated. The features of the microstructure and phase composition of samples having a UFG structure are studied.
