| Abstract: | 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, and HcJ=547 kA/m (6.87 kOe). 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 |
