纳米晶复合磁体的可能性近来对纳米晶复合磁体的研制十分关注，这种磁体是由粒径约为几十ｕｍ的软磁性晶粒（Ｆｅ或Ｆｅ３Ｂ等约４０％～８０％）和其余为硬磁性晶粒所组成。因含稀土金属很少，所以是原料成本便宜的高性能磁体。纳米晶复合磁体的特点是含有大量软磁相，软...
The possibility of nanocrystalline composite magnets recent development of nanocrystalline magnets is very concerned about the development of this magnet is about the size of the soft magnetic grains dozens of um (Fe or Fe3B about 40% to 80%) and the rest is Hard magnetic grains. Due to rare earth metals, it is a high performance magnet with low cost of raw materials. Nanocrystalline composite magnet is characterized by a large number of soft magnetic phase, soft ...
