Thermodynamics of solid Sn and Pb Sn liquid mixtures using molecular dynamics simulations
Source abstract
Abstract
Abstract We present a new set of modified embedded-atom method parameters for the Pb Sn system that describes many 0 K and high temperature properties including melting point, elastic constants, and enthalpy of mixing for solid and liquid Pb Sn alloys in agreement with experiments. Then, we calculate the phase diagram of the Sn-rich side of Pb Sn alloys utilizing a hybrid Molecular Dynamics/Monte Carlo simulation that agrees with experimental solidus and liquidus curves as well as stability of α-Sn and β-Sn. In addition, we present structure factors of Pb Sn liquid alloys as well as temperature-dependent thermal expansion coefficients and heat capacity. Our simulations show that the ratios of the heights of the second and third peaks over the first peak for Pb Sn liquid mixtures are maximum at Pb-0.6Sn concentration.
