摘要：
The isothermal section of the Er-Mn-Nd ternary system at 773 K was investigated mainly by X-ray powder diffraction with the aid of differential thermal analysis. The 773 K isothermal section of the ternary system consists of 9 single-phase regions, 14 two-phase regions, and 6 three-phase regions. At 773 K, the maximum solid solubility of Er in Nd and Nd in Er is about 20% (atom fraction) Er and 26% (atom fraction) Nd, respectively. Er6Mn23 and Nd6Mn23 form a continuous solid solution. The homogeneity range of 8 phase extends from about 38% (atom fraction) Er to 43% (atom fraction) Er. No ternary compounds were observed at 773 K in this system.
