本文从Nd-Fe-Co-B-Ga磁粉常规选区电子衍射花样研究了氢化-分解-脱附-复合（HDDR）法生产的Nd-Fe-Co-B-Ga磁粉中细晶畴的晶体取向。结果表明，Nd 2Fe 14 B型P42 mnm晶畴的c轴和a轴分别在45°的立体角内取向。c轴的相关排列解释了磁粉的磁各向异性
Crystallographic orientation of fine crystalline domains in magnet powder of Nd-Fe-Co-B-Ga produced by the hydrogenation-decomposition-desorption-recombination (HDDR) method has been examined from their conventional selected area electron diffaction patterns. It was found that the c- and a-axes of domains (Nd 2 Fe 14 B-type: P4 2 mnm) are aligned within 45° in solid angle, respectively. The correlated alignment of c-axes accounts for the magnetic anisotropy of the magnet powder
