Crystallization of single-phase nanocrystalline Nd_(10.8)Dy_(1.5)Fe_(79.7)(NbZrCu)_(2.0)B_(6.0) ribbons

摘要

The crystallization of single-phase nanocrystalline Nd_(10.8)Dy_(1.5)Fe_(79.7)(NbZrCu)_(2.0)B_(6.0) ribbons has been investigated. The as-spun ribbons are mainly composed of an amorphous matrix with a small amount of α-Fe, Nd_2Fe_(14)B and/or other crystallization phases. Cu-enriched clusters with different sizes have been found in the as-spun ribbons. These clusters almost disappear after crystallization, which can possess effects on the refinement of grains.
