CALCULATION OF THERMODYNAMIC PROPERTIES OF SN-ZN LIQUID ALLOY AT 750 K USING SELF ASSOCIATION MODEL

Abstract

The concentration effect on the free energy of mixing (SM), activity (a), and microscopic properties of a Sn-Zn binary liquid alloy, including the concentration change in the long wavelength limit (Scc) and the Warren-Cowley short range order parameter, is determined using the self-association model. The calculations indicate that the Sn-Zn liquid alloy exhibits homo-coordination or phase separation with mild interaction at 750 K, regardless of concentration.
