Abstract

The magnetic hysteretic properties of an Fe–25Cr–12Co powdered hard magnetic alloy have been studied as a function of heat-treatment conditions. The optimization of heat treatment, including thermomagnetic process, and the determination of the optimum magnetic hysteretic properties have been performed using the Statgraphics Centurion XVI software. The following parameters are obtained after the optimum heat treatment: the residual induction is up to Br = 1.425 T, the coercive force is HcB up to 46.45 kA/m, and the maximum energy product is (BH)max = 45.2 kJ/m3. Various optimum heat-treatment conditions are required to achieve the optimum values of Br, HcB, and (BH)max.
