Abstract
The thermodynamic optimization of the Ni-Sn-Bi ternary system was performed using the Calphad method and experimental data obtained by Differential Scanning Calorimetry and Scanning Electron Microscopy. The ternary phase was described using a three-sublattice model. The previously reported new ternary compound and the solubility of the third element in two binary systems (Bi in Ni-Sn and Sn in Bi-Ni) were included in the optimization. Four isothermal sections were calculated using Thermi-Calc software and compared with the experimentally obtained ones. A miscibility gap in the ternary system was found at 1610 K.
