A polydisperse hard sphere model for interatomic correlations in multi‐component metallic melts

We propose a polydisperse hard sphere model for numerical calculation of the analytic radial distribution function of multi-component atomic liquids The vibrational part of atomic thermal motion in liquids is modeled by the effective density profile of polydisperse hard spheres We applied an orthogonal polynomial technique for the solution of a system of Ornstein-Zernike equations using the hard sphere Percus-Yevick analytic expression for the direct correlation functions. The partial radial distribution functions were calculated for the case of a binary liquid where the size distribution of the components is specified by Schultz distributions
