【 摘 要 】

Effect of mixing duration and sintering temperature on the magnetic properties of hard magnetic powder alloy Fe-30Cr-8Co (wt.%) was studied. The obtained magnetic hysteresis properties of the hard magnetic powder alloy are better than as for industrial Fe-Cr-Co alloy which cobalt content is twice bigger. The optimum sintering temperature was 1350-1400 °C. At a sintering temperature of 1400 °C for 2.5 hours the mixing duration does not affect on the magnetic hysteresis properties. This technological operation is not critical.
