Abstract

The field dependences of the differential magnetic susceptibility of structural alloy steel 38KhS (an analogue of EN 1.7220 steel) are measured after quenching followed by tempering at temperatures ranging from 500 to 750°C and cold plastic deformation by tension. It is found that in highly tempered samples (above 600°C), at relative elongations exceeding 2%, features such as kinks and additional maxima appeared on the curves. The critical fields of irreversible displacement of the 90° domain walls and the fields of induced magnetic anisotropy have been calculated. Their values allow an estimation of the residual stress levels in the studied samples.
