摘要

The isothermal sections of the Nd–Mg–Ni ternary phase diagram at 1123 and 673 K (Ni-rich part) were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential thermal analysis. The 1123 K isothermal section consists of 8 single-phase regions, 14 two-phase regions and 7 three-phase regions. The 673 K isothermal section consists of 11 single-phase regions, 21 two-phase regions, and 11 three-phase regions. In addition, the existence of two ternary compounds NdMg₂Ni₉ and NdMgNi₄ has been confirmed, and the Nd₂MgNi₉, Nd₅Mg₂Ni₂₃ and Nd₃MgNi₁₄ compounds do not exist at 1123 and 673 K isothermal sections. No solid solubility was observed in our work.
