烧结Nd-Fe-B取向度的研究
Study on Alignment Degree of Sintered Nd-Fe-B Magnets
【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。
【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.
