| 摘 要： | 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强脉冲磁测量的Ｂｒ／Ｊｓ和（Ｂｒ∥－Ｂｒ）／Ｂｒ∥值进行了比较。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。

| Abstract: | A new method for evaluating the alignment degree of sintered Nd-Fe-B magnets quantitatively by X -ray diffraction measure-ments was Proposed, and the results were compared with Br/Js and (Br// -Br)/Br// measured by pulse magnetic field greater than 10T. It is proved that evaluating the alignment degree only by the relative intensity rate of I(105)/I(006) is not fully reasonable. To improve the alignment degree of sintered Nd - Fe - B magnets on die pressing conditions, taking technologic measures such as increasing aligning magnetic field or minimizing frictions of Powders and dies is necessary. |
