Zusammenfassung:Heat treatment of Fe–30Cr–12Co magnetically hard anisotropic powder alloy was optimized. The best magnetic hysteresis characteristics are the following: residual magnetic induction B r = 1.262 T, coercive force H c B = 47.55 kA/m, and the maximum energy product ( BH ) max = 38.4 kJ/m 3 . Regression equations of the dependences of magnetic hysteresis characteristics on the parameters of heat treatment of the alloy under study were obtained, which adequately describe these dependences in phase spaces within the oscillations of the chosen parameters. At the cobalt content that is two times lower than that in the YuND14K24 industrial alloy (GOST 1780972) [1], the alloy possesses practically equivalent magnetic hysteresis characteristics.
