Abstract
Magnetic hysteresis properties (residual induction Br, coercivity Hc and maximum energy product (BH )max) of Fe – 27% Cr – 10% Co (27Kh10KA) hard magnetic powder alloy are assessed after different heat treatments. Optimum modes of heat treatment are determined using TRM251 programmed derivative-proportional-integral controllers. The magnetic characteristics of the specimens exceed those of the widely used alloy 25Kh15KYuBF with a higher cobalt content. The prospects of the Fe – 27% Cr – 10% Co (27Kh10KA) powder alloy for commercial production are considered.
