| 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. |
| Keywords: | Sm2Fe17N3/Fe3N/BN soft/hard magnetic composite material high-energy ball-milling vacuum annealing |
