【 摘 要 】

Magnetic hysteresis properties of powder hard magnetic Fe-27Cr-10Co alloys with 0.5 and 2.0 wt % molybdenum were studied. For Fe-27Cr-10Co-0.5Mo alloy: Br= 1.35 T, HcB= 45.6 kA/m and (BH)max= 41 kJ/m3. For Fe-27Cr-10Co-2Mo alloy: Br= 1.29 T, HcB= 41 kA/m, (BH)max= 34.8 kJ/m3. It was shown that an alloying with 2 wt. % molybdenum of the low-cobalt powder hard magnetic Fe-27Cr-10Co alloy unlike high-cobalt hard magnetic FeCrCo alloys did not increase its magnetic hysteresis properties, reduced the camber of a demagnetization curve in a second quadrant.
