为树脂粘结磁体应用开发了低稀土含量的高剩磁、各向同性磁粉。该材料基于亚稳Fe（Fe，Co）/sub 3/B-Nd/sub 2/Fe/sub 14/B纳米晶体混合物，并添加少量Al、Si、Cu、Ga、Ag和Au中的一种。利用透射电镜研究了添加剂对合金微观结构的影响。结果发现，添加剂显着降低晶粒尺寸，这导致在材料的磁滞矩形度的改善。本文详细介绍了Nd/sub 4.5/Fe/sub 73/Co/sub 3/Ga/sub 1/B/sub 18.5/粘结磁体的磁性能。>
High-remanence, isotropic magnetic powder of a low rare earth content is developed for resin-bonded magnet applications. The materials are based on a metastable Fe(Fe, Co)/sub 3/B-Nd/sub 2/Fe/sub 14/B nanocrystalline mixture with the addition of a small amount of one of Al, Si, Cu, Ga, Ag, and Au. The effects of the additives on the microstructure are investigated by means of transmission electron microscopy. It is found that the additives considerably reduce grain sizes, which results in improvements in the hysteresis squareness of the material. The magnetic properties of a bonded magnet produced from Nd/sub 4.5/Fe/sub 73/Co/sub 3/Ga/sub 1/B/sub 18.5/ are described in detail. >
