摘要	The effects of the addition of Mo alone and the addition of Mo pins Co an the structure and magnetic properties of mechanically alloyed Nd8.4Fe87.1B4.5 alloy were studied. Both the addition of Mo alone and the addition of Mo plus Co result in an increase in the Curie temperatures of the hard phases. The addition of Mo alone, especially for the 1.6 at% Mo-added case, results in the improvement of the intrinsic coercivity H-0(c) and the maximum magnetic energy product (BH)(max). The addition of Mo alone results in refinement of alpha-Fe grains but in coarsening of the hard grains. The addition of both Co and Mo can both refine the soft grains and inhibit the trend of coarsening of the hard grains due to the addition of Mo alone. The best magnetic properties: mu(0)H(c) = 0.58 T (5.8 kOe), J(r) = 1.04 T (10.4 kG), (BH)(max) = 113.8 kJ m(-3) (14.3 MGOe), J(r)/J(s) = 0.68, are achieved for the Nd8.4Fe80.4Co5.6Mo1.1B4.5 alloy.
