Abstract

Phase relationships in the Nd-Ce-Fe ternary system at 773 K have been investigated mainly by x-ray diffraction and scanning electron microscopy with energy disperse spectroscopy techniques. The isothermal section consists of 6 single-phase regions, 7 two-phase regions and 3 three-phase regions. No ternary compound is observed in this system. Nd2Fe17 and Ce2Fe17 are found to form a continuous solid solution (Nd,Ce)2Fe17, and the solubilities of Ce in Nd5Fe17 and Nd in CeFe2 are determined.
