利用扫描电子显微镜和X射线衍射仪研究了双相复合永磁合金快淬带的织构与形貌。结果表明合金快淬带自由面存在择优取向。与三元Nd -Fe -B合金相比 ,复合添加Dy和Ga具有增加合金快淬带织构和细化组织形貌的作用 The texture and morphology of the rapidly quenched ribbons of dual phase composite permanent magnetic alloys were investigated by scanning electron microscopy and X-ray diffraction. The results show that the free surface of the alloy has the preferred orientation. Compared with the ternary Nd-Fe-B alloy, the addition of Dy and Ga has the effect of increasing the texture of the quenched zone and refining the microstructure of the alloy
