摘要：

The present work describes the developments of hard magnets by thermo-magnetic treatment. The magnetic properties of Fe-28Cr-15Co-(1-5)Mo (wt%) alloys after different heat treatment conditions are studied and compared with ternary Fe-28Cr-15Co alloys. Fe-28Cr-15Co-3.5Mo have produced a coercive force of 840 Oe (66.83 kA/m), remanence of 11 kG (1.1 T) and energy product of 5.4 MGOe (43 kJ/m(3)) that are comparable to Alnico 6 magnets. It was found that addition of Mo up to 3.5 wt% to the ternary alloys causes to extend the alpha-phase microstructure at annealed state and stimulates the spinodal decomposition of Fe, Co-rich alpha(1)-particles in a preferred direction [100] that leads to increase the magnetic properties of the alloys.
