摘要：
Ingots of composition Nd9Fe85B6, Nd9Fe85B6 + 1 at.% (Ti + C), Nd9Fe85B6 + 2 at.% (Ti + C), and Nd9Fe85B6 + 5 at.% (Ti + C) were prepared by plasma are-melting the constituent elements from 99.95 wt% Nd, 99.99 wt% Fe, 99.97 wt% Ti, spectrographic grade C, and ferroalloy Fe-B (19.6 wt% B). Effect of Ti + C addition and its content on quenchability and magnetic properties of Nd9Fe85B6 alloy were investigated by melt-spinning. The results showed that the added Ti and C elements reacted with each other to form TiC compound that was solid solutioned, precipitated, or both in the cast ingots. The Ti + C addition can increase the glass-forming ability (GFA) of an alpha-Fe/Nd2Fe14B-type nanocomposite permanent material: the more the additive, the stronger the GFA; but only approximately 2 at.% Ti + C addition could enormously increase the magnetic properties.
