Abstract

The magnetic properties of deformable magnetically hard alloy Fe – 27.5% Cr – 7.9% Co – 0.3% V – 0.65% Si – 0.4% Ti are studied after isothermal thermomagnetic treatment (ITMT) optimized using the method of experimental design. Mean values of residual induction B r, coercive forces H ci (with respect to induction) and H cm (with respect to magnetization), and maximum energy product (BH)max after optimum ITMT are determined. A three-dimensional dependence of the coercive force H cm on the temperature and time of the ITMT is plotted.
