本研究通过控制熔融纺丝制备了具有强晶体织构的α-Fe/Nd2Fe14B纳米复合磁体。对于 10 m/s 的相对较低轮速，Nd2Fe14B 晶体的 c 轴织构主要垂直于带材平面，但在 20 m/s 的较高轮速下，其转为平行于带材平面方向。磁体在带状平面内外表现出很强的磁各向异性。在轮速为 20 m/s 时制备的磁体中，平行于带状平面方向观察到了 0.74Ms 的高剩磁和 24.3 MGOe 的大磁能积。
In this study, α-Fe/Nd2Fe14B nanocomposite magnets with strong crystallographic texture were prepared by controlled melt spinning. For a relatively low wheel speed of 10 m/s, the c-axis texture of the Nd2Fe14B crystals is predominantly perpendicular to the plane of the ribbon, but it switches to parallel to the ribbon plane direction at a higher wheel speed of 20 m/s. The magnets show strong magnetic anisotropy between in and out of the ribbon planes. High remanence of 0.74Ms and a large energy product of 24.3 MGOe were observed parallel to the ribbon plane direction in the magnets prepared at a wheel speed of 20 m/s.
