用Mossbauer谱探讨甲苯对NdFeB性能的影响

EFFECT OF TOLUENE ON PROPERTY OF NdFeB BY USING MOSSBAUER SPECTRUM

本文利用Ｍｏｓｓｂａｕｅｒ谱和退磁曲线探讨粉末冶金工艺生产的ＮｄＦｅＢ稀土强永磁合金材料的超精细磁场强度，研究在实际生产过程中防氧化保护介质甲苯的含量不同对磁体性能的影响．

The essay probes into the intensity of the super-fine magnetic force of Nd-Fe-B produced with the technology of powder metallurgy by way of Mossbauer spectrum and de-magnetization cune. It deals with the effects of the different contents of toluene,the anti-oxi-dation medium,on the property of maghets during actual production process.
