Abstract

An austenitic natural composite structure reinforced with nanosized carbides (Fe100– xMnx)3C was first formed in classical Hadfield steel (Fe–13Mn–1.1C) under superplastic deformation. The mechanism and kinetics of dynamic strain aging of the steel under high-pressure torsion in Bridgman anvils were revealed. It was shown that increasing the strain and temperature of deformation caused an anomalous acceleration of dynamic strain aging of the steel with the formation of nanosized carbides (Fe100–xMnx)3C.
