摘要	The effect of Co substitution on the structure and magnetic properties of mechanically alloyed Pr14Tb,Fe76-xCOxC6B2 and Pr16Fe76-x,COxC6B2 (x = 0-20) alloys has been studied systematically. The main phase in the alloys is Pr2Fe14C-type carbide, coexisting with a small amount of alpha-Fe and rare-earth-rich phases. In addition to the increasing of the Curie temperature of the Pr2Fe14C-type phase, Co substitution can affect the magnetic properties by adjusting the alpha 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 alpha-Fe fraction with a small Co addition. The highest coercivity H-i(c) of 20.3 kOe and the optimum energy product (BH)(max) of 10.3 MG Oe have been obtained for the Pr14Tb2Fe69.5C06.5C6B2, alloy. (c) 2005 Elsevier B.V. All rights reserved.
