稀土－铁永磁合金Ｒ_（１－α－β）Ｘ_αＦｅ_β稀土－铁金属间化合物有可能获得大的晶体磁各向异性、高的饱和磁化强度、高矫顽力和高磁能积的永磁材料，比传统的稀土钻永磁合金便宜得多。但一般稀土－铁二元系永磁合金的矫顽力都较低，因而在应用上受到很大限制。为了?.. Rare earth-iron permanent magnet alloy R_ (1-α-β) X_αFe_β rare earth-iron intermetallic compounds It is possible to obtain permanent magnet materials with large crystal magnetic anisotropy, high saturation magnetization, high coercivity and high magnetic energy product , Much cheaper than the traditional rare earth permanent magnet alloy. However, rare earth - iron binary system permanent magnet alloys are relatively low coercivity, which is greatly restricted in application. in order to?..
