Thermo-physical properties of ternary Al–Cu–Fe alloy in liquid state

Abstract

The thermodynamic and surface properties of the ternary Al–Cu–Fe alloy in the liquid state have been computed using different models. The thermodynamic properties, such as activity and excess free energy of mixing and the surface properties, such as surface tension have been calculated. The temperature dependence of activity and surface concentration of the components of the ternary Al–Cu–Fe alloy in fixed proportion of any two components have also been calculated. The surface tension of the alloy with respect to the change in temperature in the range 1823–2073 K has also been studied.
