The optimization of heat treatment of an anisotropic hard magnetic Fe–30Cr–16Co–1Sm powder alloy is performed by experimental design using the Statgraphics and Statistica software. After optimization, the remanence is Br = 1.252 T, the coercive force is HcB = 53.08 kA/m, and maximum energy product is (BH)max = 36.8 kJ/m3. Adequate regression equations of the dependences of Br, HcB, and (BH)max on the heat treatment parameters (holding time during isothermal thermomagnetic treatment (ITMT), cooling rate from the ITMT temperature to 580°C, and cooling rate from 580 to 500°C) within variations of selected parameters in corresponding phase spaces are obtained. The studied magnetic hysteretic properties of the Fe–30Cr–16Co–1Sm alloy exceed those of one of the most widely used commercial alloys, YuNDK4 (GOST 17809–72) [1], by more than 40% at a lower cobalt content.
