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. Nd 2 Fe 17 and Ce 2 Fe 17 are found to form a continuous solid solution (Nd,Ce) 2 Fe 17 , and the solubilities of Ce in Nd 5 Fe 17 and Nd in CeFe 2 are determined.

773 K 时 Nd-Ce-Fe 系统中的相关系

Nd-Ce-Fe 三元体系在 773 K 下的相关系主要通过 X 射线衍射和扫描电子显微镜和能量色散光谱技术进行了研究。等温段由6个单相区、7个两相区和3个三相区组成。在该系统中未观察到三元化合物。发现Nd 2 Fe 17 和Ce 2 Fe 17 形成连续固溶体(Nd,Ce) 2 Fe 17 ，并测定Ce 在Nd 5 Fe 17 和Nd 在CeFe 2 中的溶解度。
