摘　　要：采用熔体快淬及晶化热处理工艺制备Nd10Fe75Co5Zr3Cr0.5B6.5纳米晶合金。快淬薄片(17m·s-1)在710℃,4min晶化处理后,晶粒尺寸为50nm^60nm。该快淬薄片经710℃,4min晶化处理后制成的粘结磁体的磁性能为:Br=0.67T,JHc=707kA·m-1和(BH)max=74kJ·m-3。Nd10Fe75Co5Zr3Cr0.5B6.5 magnet was prepared by melt-spun and subsequently annealed. After treated at 710℃ for 4 min, the mean grain size of the ribbon was 50 nm^60 nm. The excellent magnetic properties of the bonded magnet were achieved: Br = 0.67 T, JHc=707 kA·m-1 and (BH)max=74 kJ·m-3.
