Abstract
The tensile test of steels St3 (GOST 380 − 94) and 40X (GOST 4543 − 2016) in an external constant magnetic field with an induction of 1,2 T was performed. Deformation energy absorption is a manifestation of the magnetoplastic effect. The similarity of the action of a magnetic field in tensile testing of samples and in the study of classical magnetic resonance is described. A new method for analyzing the magnetoplasticity of bulk samples by analogy with the construction of the energy absorption spectrum at magnetic resonance has been applied. The energy absorption spectrum is plotted in the coordinates of the metal flow stress – dislocation density. The characteristics of the spectrum line are determined: its depth as the value of the absolute decrease in the metal flow stress, as well as its width according to the FWHM (Full With at Half Maximum) value.
