Abstract

High-performance powders of NdFe_10.5V_1.5N_x with B_r = 10.8 kG, H_cJ = 4.3 kOe, (BH)max = 17.2 MGOe, and T_c > 800 K were successfully prepared by using conventional milling process. The relationship of the crystallographic structure and the intrinsic magnetic properties to the nitrogen content is investigated. It is found that the nitrogen content is vital to obtain high-performance magnetic powders based on NdFe_10.5V_1.5N_x. In comparison with quenching Nd-Fe-B powders, NdFe_10.5V_1.5N_x powders are characterized by a larger maximum-energy product and a lower cost. Obviously, it is of significance in permanent magnet applications.
