Evaluation of the relative quantity of residually compressed grains in steels after their plastic extension on the basis of remanent magnetization

The percentage of residually compressed grains was evaluated on the basis of previously obtained experimental data on the change in the remanent magnetization of steel upon unloading after a plastic extension. In this case, only grains in which the residual compressing stresses exceeded the initial (before plastic deformation) average internal deformations of the first type, which resulted in changing their domain structure to the easy-plane type of state, were considered.
