对 Nd2 Fe14 B 快淬薄带进行热晶化处理和机械合金化处理，通过样品的 XRD 图和磁滞回线图，分析了薄带和磁粉的晶粒尺寸及矫顽力的变化规律。结果发现，机械合金化得到的磁粉具有更大的矫顽力，并且磁粉矫顽力的增强是由于晶粒尺寸的减小所致，而不是由于形成织构造成的。

In this paper,the melt spun Nd2 Fe1 4 B ribbons were treated by annealing and mechanical alloying.The variation of grain size and coercivity of the ribbons were studied by XRD study and the hys-teresis loops obtained in the ribbon and powder.The powder prepared by mechanical alloying shows larger coercivity than that of the ribbon,which is due to the decrease of the grain size instead of forming texture.
