Abstract

Abstract: Effects of cold deformation and recrystallization heat treatment on hardness of hot-rolled Fe-Mn-Cr-C series high manganese austenitic cryogenic steel with deformation of 0, 12.5% and 50% were studied by means of EBSD, XRD, tensile test and hardness test. The results show that microstructure of the steel is still single austenite and no new phase is observed after cold deformation. With the increase of cold deformation, the quantity of twins in the steel increases. When the deformation is 12.5%, the deformation twins are formed in a small number of grains. When the deformation is 50%, the deformation twins are dense and intersecting with each other. The hardness of the steel increases from 262 HV to 400 HV with the increase of deformation from 0 to 50%, and decreases to 179 HV and 166 HV respectively after recrystallization heat treatment.
