摘要：

采用高能球磨和真空热处理方法制备Sm2Fe17N3/Fe3N/BN复合材料, 并研究球磨过程中晶粒尺寸变化对固态相变和磁性能的影响. 结果表明: Sm2Fe17N3和Fe3N相产生的条件是Fe的晶粒尺寸达到纳米量级（D＜80 nm）并形成Fe(Sm)固溶体; 随着退火时间的增加, 300 ℃真空退火的球磨样品中Sm2Fe17N3的结晶物增多, 矫顽力提高, 表明样品的磁性能与Sm2Fe17N3的结晶程度有关.

Abstract:

Sm2Fe17N3/Fe3N/BN composite magnetic material was prepared by means of high\|energy ball\|milling and vacuum annealing treatment. Solid\|state phase transformation and magnetic performance were investigated. The results show that the conditions of the generation of Sm2Fe17N3 and Fe3N are the grain size of Fe comes up to nanometre (D＜80 nm) and forms Fe(Sm) solid solution. The crystal substance of Sm2Fe17N3/Fe3N/BN in the ball\|milling material vacuum annealing at 300 ℃ was increased and coercivity was increased with increasing annealing time. That is magnetic property of the sample has something to do with the degree of crystallinity of Sm2Fe17N3.

Key words: Sm2Fe17N3/Fe3N/BN, soft/hard magnetic composite material, high\, energy ball\, milling, vacuum annealing
