Characteristic of the changes in magnetic properties of heat-treated steel at the early stages of cold plastic deformation by tensile strain

Abstract: The present work establishes alloy steel 38KhS exhibits distinct features such as an inflection point and a second peak in the field dependencies of differential magnetic susceptibility only in samples with ε = 4 % and tempering temperatures of 650 and 700 °C, unlike annealed low-carbon steel. The absence of such characteristics on the χd(H) curves for samples with ε = 2 % and Ttemp 650 °C is likely due to the high level of randomly distributed internal stresses remaining after heat treatment. These stresses prevent the formation of an «easy plane» magnetic texture after plastic deformation by stretching.
