摘要：

Sm2Fe17Nx powders were prepared through metallurgical processes such as melting, casting, pulverizing, and gas nitrogenation. Epoxy resin and zinc-bonded magnets were prepared from the powder by a compression molding process. The magnetic properties of magnetically aligned Sm2Fe17Nx powder were (BH)max = 170 kJ/m3 (21.4 MG . Oe), Br = 1.20 T, H(cJ) = 547 kA/m (6.87 kOe), and those of an epoxy-bonded magnet were (BH)max = 103 kJ/m3 (13.0 Mg . Oe), and Br = 0.835 T. H(cJ) values in excess of 2 MA/m (25 kOe) were observed in the case of a zinc-bonded magnet.
