Solidification and crystallization behaviors of Fe3B/Nd2Fe14B-based nanocomposite permanent-magnet alloys and influence of micro-alloyed Cu, Nb and Zr
Description
Rapid solidification process of Nd2Fe14B-based nanocrystalline permanent-magnet alloys and crystallization processes of the relevant amorphous alloys are investigated. Accumulated experimental results are discussed in terms of temperature-time-transformation diagrams for Nd4Fe77.5B18.5. Solidification and crystallization kinetics is strongly influenced by minor amounts of additives, particularly Cr, Cu, Nb, and Zr, knowledge of which has been applied to design alloy composition. Development of a high coercivity Fe3B/Nd2Fe14B-type nanocomposite magnet based on Nd-Dy-Fe-B-Cr-Co-Cu-Nb/Zr is described as an example
