Abstract

The dependence of the direction and degree of short-range ordering on the temperature of severe plastic deformation has been determined in the Fe_86.8Cr_13.2 binary alloy using Mossbauer spectroscopy. The stratification decreases upon cold (80–298 K) deformation and increases upon warm (453–573 K) deformation. The enhancement of stratification during warm deformation is caused by the continuous generation of point defects and their increased mobility.
