摘要：
The synthesis of magnetically anisotropic Sm2Fe17Nx + alpha-Fe composite powders was tried by Sm evaporation from the Sm-Fe mother alloy at 1273 K in a vacuum, mechanical grinding (MG) in NH3 and nitriding. The powders were composed of the Sm2Fe17Nx + alpha-Fe phase, possessed a magnetic anisotropy, and showed a reversible magnetization reaching 66.8%. (C) 2002 Acta Materialia Inc.
