Abstract: Mechanical milling has been applied to prepare Nd-Fe-Mo magnetic powders. For preparing the single-phase Nd1.5Fe10.5Mo1.5 compounds with ThMn12-type structure, a mixture of amorphous phase and α-Fe was obtained by ball milling for 4~18 h. In the process of ball milling, the powders went through breaking and recombining, which were closely related to amorphous formation. The powders of nanostructured 1∶12 phase was formed after annealing at 700~850℃ for 10~40 min. The optimum magnetic properties were obtained with the following nitriding treatment at 500~550℃ for 1~2 h.
