Thermodynamic, transport and surface properties in In–Pb liquid alloys

Abstract

Thermodynamic, transport and surface properties of liquid In–Pb alloys have been investigated using the simple statistical model. The free energy of mixing, heat of mixing, entropy of mixing and activity of components of liquid alloys In–Pb at 637K have been computed. The microscopic function, concentration–concentration fluctuations in long wavelength limit have been studied to investigate the stability and microscopic structural information about liquid alloys and chemical short range order parameter has been calculated to quantify the degree of atomic order. The same energy parameters have been used to compute diffusion coefficients ratio, viscosity, surface tension and surface concentration of liquid In–Pb alloys. The study reveals that liquid In–Pb alloy is weakly interacting and phase separating system.
