A study of thermodynamics of mixing for Al1 −xSnx liquid binary alloy

Thermodynamics of mixing namely the energy of mixing (ΔA), enthalpy of mixing (ΔH) and entropy of mixing (ΔS) for Al1 −xSnx liquid binary alloys are studied theoretically by using the electronic theory of metals (ETM) within the purview of the perturbation theory and the statistical mechanics at T = 973 K. Here, the electron-ion and ion-ion effective interactions are described by a local pseudopotential. This is the first microscopic study for the concerned system, to the best of our knowledge. However, results of our calculations agree very well with the available experimental data.
