摘要：
A technique for producing Sm2Fe17 from cast ingots without the presence of free iron has been developed which involves the addition of between 4 and 5% Nb to the melt. The free iron is thereby replaced by paramagnetic NbFe2. A nitriding procedure for this material in N2 gas to produce Sm2Fe17N3-delta with delta almost-equal-to 0.3 is described.
