永磁材料未来十年研究展望

Prospects of Permanent Magnetic Materials for Future Decade

在未来的１０年里，永磁材料的研究与开发将主要呈现３个特点：磁体性能综合化、合金成分多元化和制备工艺高技术化。ＮｄＦｅＢ系合金，Ｓｍ２Ｆｅ１７Ｎｘ（ｘ＝２～３）系合金仍将是研究的热点。除此之外，复合型双相纳米晶永磁合金，Ｒ３（Ｆｅ，Ｔ）２９Ｚｙ（Ｒ＝ＲＥ；Ｔ＝Ｃｒ，Ｖ，Ｔｉ；Ｚ＝Ｃ，Ｈ，Ｎ）３∶２９类化合物将吸引越来越多的注意力。本文重点综述了双相纳米晶永磁合金和３∶２９类化合物的研究进展，并对今后永磁材料的研究方向作了简略的展望。

In future decade, the research & development of permanent magnetic materials may concentrate mainly on synthetic property of magnet, multi element alloy and high tech producting process. NdFeB system and Sm 2Fe 17 N x ( x =2～3) system will still be the hot points of study, and besides these, dual phase nano grain rare earth permanent magnetic alloys and R 3(Fe, T ) 29 Z y (R=RE; T =Cr,V,Ti; Z =C,H,N) (3∶29 system compounds) will attract more and more attention of researchers. The developments of dual phase nano grain rare earth permanent magnetic alloys and 3∶29 system compounds are introduced emphatically, and some possible research trends of future permanent magnetic materials are predicted briefly.
