Tensile tests of plastically deformed specimens were performed in order to investigate the relation between variation of magnetic characteristics and residual plastic strain. Deformed stainless steel (SUS316L) and carbon steel (SS400) speciments were investigated by the method of Magnetic Adaptive Testing, measuring and evaluating series of minor magnetic hysteresis loops.Correlations were found between magnetic parameters and residual strain of the specimens. Magnetic descriptors also on the orientation of magnetizing field with respect to the direction of elongation. Based on these results, MAT is suggested as a highly promising non-destructive method for monitoring plastic deformation in different types of steel .
