Abstract
The phase equilibria of the Cu-Nb-Ni system were investigated via a combination of key equilibrated alloys and thermodynamic modeling. Twelve different compositions of ternary alloys were prepared to determine the isothermal sections at 700, 800 and 900 °C, by means of x-ray diffraction and scanning electron microscopy with energy dispersive x-ray spectroscopy. The three- and two-phase regions were determined. The solubilities of the NbNi3 and Nb7Ni6 phases were measured. No ternary compound was found in this ternary system. Based on the experimental equilibria data from the literature and the present work, a thermodynamic description of the Cu-Nb-Ni system was carried out by using the CALPHAD (CALculation of PHAse Diagrams) method. The substitutional model and sublattice model were employed to describe the solution phases and intermediate phases, respectively. A set of self-consistent thermodynamic parameters of the Cu-Nb-Ni system was conclusively obtained. Most of the reliable experimental data were reproduced by the present thermodynamic modeling.
