摘　　要： 采用快淬法制备了Fe74Cu1Nb3Si13B9非晶薄带,然后将薄带晶化,粉碎成不同粒度的磁性粉末。选择固态环氧树脂作为粘结剂,按一定比例将粘结剂与磁粉混合,在不同的压力下将其压制成Fe基纳米晶环形粘结磁体。分析了不同的磁粉粒度和模压压力对粘结磁体磁性能的影响,结果表明,随着磁粉粒度的减小,μi,μm,Bs,Br,Hc也随之减小;当压力增加到180kN时,再增加压力,磁性能变化不大。 The Fe74Cu1Nb3Si13B9 ribbon thin amorphous has been produced by rapid quenching and the ribbon after crystallined has been pulverized to magnetic powder in different particle size.Mixing magnetic powder with epoxy resin binder in the proportion, the ring magnets with nanocrystalline were formed with different pressure. Influence of magnetic powder particle size and forming pressure the on the magnetic properties of the bonded magnet is analyzed. The results show that the μ,μm,BB,BT,HC decreases with decrease the of the particle size of magnetic powder, and increases with the increase pressure until to 180 kN.
