The Effects of Ti, C, and TiC on the Crystallization of Amorphous Nd2Fe14B.

-The effects of Ti, C, and TiC alloying additions on the energy products obtained by crystallization from an amorphous Nd2Fe14B precursor are studied. The increase of the as-crystallized energy product is attributed to a more uniform microstructure due to enhanced nucleation of the hard magnetic phase and to the formation of soluble carbide and boride phases serving as nucleation promotors. The increase of the crystallization temp. of the glass caused by addition of Ti and TiC leads to a uniform fine-grained microstructure. The formation of high as-crystallized energy products requires very low equilibrium solubilities of the alloying additions in the Nd2Fe14B phase. Additives which reduce the amount of the hard magnetic phase or cause formation of other soft magnetic phases are not effective. -(BRANAGAN, D.
