摘　　要：研究SmFeN稀土永磁材料球磨法制备过程和材料性能。Sm-Fe母合金合适的Sm补偿量为20%,氮化前最佳的球磨时间为为1.5h,合金氮化后为各向同性的粗磁粉,经过进一步球磨细化后,可以得到各向异性的性能高的磁粉。The preparation process and magnetic properties of SmFeN type rare-earth metal permanent magnetic material by the powder metallurgic method are investigated.The proper Sm compensate of Sm-Fe alloy is 20%,the best milling time before nitrogenation is 1.5h,the alloy is the thick isotropy magnetic powder after the very nitration process,and the powder becomes the anisotropy magnetic powder with high properties through further refining by milling.
