本文在分析烧结NdFeB取向度的各种计算方法的基础上,提出一种新的计算方法.采用这种方法,仅利用烧结体垂直于外加磁场方向截面的X射线衍射谱,通过简单的计算就能很容易的计算出磁体的取向度.
The methods evaluating the alignment degree of the sintered NdFeB permanent magnets have been reviewed and a new quantitative evaluation method has been proposed in this article.In this new method,the alignment degree can be easily achieved by simple calculation through the X-ray diffraction spectrum crossing the plane normal to the applied field direction.
