摘　　要：研究了Sm2Fe17Nx粉末的球磨工艺条件对粉末磁性能的影响。在球磨筒的装球量达到合适的填充系数的情况下，适当增大料球比对粉末磁性能改善是有益的。粉末平均粒径1．2～1.5um为最佳。文中对影响机理作了分析说明。The influence of milling process for nitrogenated powder Sm2Fe17Nx on itsmagnetic properties has been investigated in this paper. With suitable ratio of ball volume to ballmilling container,moderate increase of the milled stuff' S quantity is beneficial to magnetic properties of acquired Sm2Fe17Nx powder. The optimum mean particle size is found to be 1. 2~ 1. 5 um.
