提出了一种用普通X射线衍射谱定量测量烧结Nd－Fe－B磁体取向度的简单易行的新方法，并与用10～12T强脉冲磁场测量的Br／Js和（Br／／→Br）／Br／／值进行了比较。通过实验证明，单用X射线衍射谱中（105）与（006）晶面的相对衍射强度比I（015）／I（006）来讲估Nd－Fe－B磁体的取向度是不妥的。为提高在金属模压工艺条件下的取向度，应加大取向外磁场或者采取减小磁粉与模具之间摩擦力的措施。
A new simple and easy method for quantitatively measuring the orientation degree of sintered Nd-Fe-B magnets by ordinary X-ray diffraction spectroscopy is proposed. Compared with the Br / Js and (Br // → Br ) / Br // values were compared. It is proved by experiment that the relative diffraction intensity ratio (015 (I) / I (006)) of the (105) and (006) planes in the single X-ray diffraction spectrum is not proper to evaluate the degree of orientation of the Nd-Fe- . In order to improve the degree of orientation under the metal molding process conditions, we should increase the orientation of the external magnetic field or take measures to reduce the friction between the powder and the mold.
