Investigation Of Easy Axis Orientation Of Nd-Fe-B Melt-Spun Ribbons Produced By Hot Rolling And Influence Of Ti-C Addition
JOURNAL OF APPLIED PHYSICS(2012)
Abstract
The c-axis orientation of Nd-Fe-B melt-spun ribbons caused by hot rolling and the influence of Ti-C addition were investigated. A small roll was placed on a steel wheel near a quartz tube in such a manner that the melt-spun ribbons were hot rolled immediately after quenching. X-ray diffraction patterns measured on both surfaces of the Nd-Fe-B-Ti ribbon indicate that the c-axis is oriented normal to the ribbon plane. The domain pattern of the Nd-Fe-B-Ti-C ribbon was observed with a Kerr microscope. Most of the grains exhibit a maze domain configuration, indicating that the c-axis is oriented normal to the ribbon plane. Furthermore, it was demonstrated that hot rolling and the addition of Ti-C promote c-axis orientation and high coercivity of Nd-Fe-B melt-spun ribbons. (C) 2012 American Institute of Physics.
