The texture and topography of melt-spun ribbons of nanocrystalline two-phase permanent magnetic alloys was studied by X-ray diffractometry and scanning probe microscopy. It was found that a pronounced preferred orientation existed in the free-side surface of melt-spun ribbons. Compared with ternary NdFeB alloy, adding Dy+Ga can increase the texture in free-side surface and refine the microstructure and topography of the ribbons.
