Abstract

Curie temperatures of RaFe17 and RTiFe,, (R=rare earths) can be raised drastically by addition of interstitial nitrogen. Can one see similar effects in NdZFellB? This question is particularly interesting because NdzFe14B’s relatively low Curie temperature has limited its applications in high temperature operations. Nitrogen additions by heat treating Nd,Fe,,B in flowing N2 at different temperatures have been reported to raise its Curie temperature by 20-50 “C. We report an attempt of nitriding Nd,Fe,,B by mechanical alloying it with Li3N. Our attempt resulted in the formation of a rare form of neodymium nitride, NdN*. The original goal to nitride NdZFe14B by mechanical alloying it with Li,N seems to be inapplicable.
