Abstract: The thermodynamic properties of liquid binary and ternary alloys in Ni-Cr-Co system, obtained by FactSage thermodynamic calculations, are presented. Thermodynamic calculations for three binary systems – Ni-Cr, Ni-Co and Cr-Co and ternary Ni-Cr-Co system, involved thermodynamic determination of activities, coefficient of activities, partial and integral values for enthalpies and Gibbs energies of mixing and excess energies at four different temperatures: 2,000 K, 2,173 K, 2,200 K and 2,273 K, as well as calculation of phase diagrams for the investigated binary systems.

Keywords: thermodynamic properties; 3D transition metals; nickel; chromium; cobalt; liquid alloys; liquid binary alloys; ternary alloys; temperature; phase diagrams; FactSage; Ni-Cr-Co.
