Nd-Mg-Ni phase diagram; ternary isothermal section; X-ray diffraction
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 I I single-phase regions, 21 two-phase regions, and I I 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. (c) 2006 Published by Elsevier B.V.
