Abstract

High-performance powders of NdFe10.5V1.5Nx with Br = 10.8 kG, HcJ = 4.3 kOe, (BH)max = 17.2 MGOe, and Tc > 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 NdFe10.5V1.5Nx. In comparison with quenching Nd-Fe-B powders, NdFe10.5V1.5Nx powders are characterized by a larger maximum-energy product and a lower cost. Obviously, it is of significance in permanent magnet applications.
