New Crystallographic Textures of Nd2Fe14B/α-Fe Nanocomposite Materials Prepared by Controlled Melt Spinning
In Nd9.5Fe84B6.5 melt-spun ribbon, the quenching temperature is found to be effective for the texture development of Nd2Fe14B nanocrystals. For a relatively low quenching temperature of 1250°C a (00l) texture of Nd2Fe14B crystals was found on the free-side surface of the ribbons. At a higher quenching temperature of 1350°C, the microstructure of the free-side surface of the ribbons switches into (320) and (517) texture. It is believed that the transformation of the melt at higher temperature triggers the switch of the texture.
