On the Possibility of Evaluating Magnetostriction Characteristics of Bulk Ferromagnets Based on Their Magnetic Properties

Based on experimental research, a relationship has been established between the critical fields, which are determined by the shape of the magnetization curve and major hysteresis loop of bulk samples of iron–carbon alloys, with the magnitude of a positive maximum of magnetostriction in these samples. By varying the annealing temperature of cold-deformed 20G steel, it has been shown that the studied critical fields are much more sensitive to changes in the stress-strain state than the known coercive force and residual induction.
