Abstract
The effect of Co substitution on the structure and magnetic properties of mechanically alloyed Pr 14Tb 2Fe 76− x Co x C 6B 2 and Pr 16Fe 76− x Co x C 6B 2 ( x = 0 – 20 ) alloys has been studied systematically. The main phase in the alloys is Pr 2Fe 14C-type carbide, coexisting with a small amount of α-Fe and rare-earth-rich phases. In addition to the increasing of the Curie temperature of the Pr 2Fe 14C-type phase, Co substitution can affect the magnetic properties by adjusting the α-Fe fraction of the alloys. The increase of both coercivity and remanence has been realized in a certain composition range. This increase may be attributed mainly to the enhancement of the effective anisotropy constant K eff of the magnets due to the reduced α-Fe fraction with a small Co addition. The highest coercivity i H c of 20.3 kOe and the optimum energy product (BH) max of 10.3 MG Oe have been obtained for the Pr 14Tb 2Fe 69.5Co 6.5C 6B 2 alloy.
