摘要

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.
