| Abstract: | The microhardness of ferromagnets is studied as a function of an external magnetic field. The maximum values of the relative change in microhardness during measurement without a field and in a magnetic saturation field for low-carbon iron, Kh16 steel, and the powder alloys Fe-TiC (ferroTiC) and PG-KhN80SR-4 are 20–34%. The effect of various processes of change in the magnetic structure on the measured microhardness of the ferromagnet is examined. A relation is established between the effect and the change in magnetic energy due to external stresses.Tula State Technical University.
