Thermodynamic database, created in the Masaryk university Brno and in the Institute of Physics of Materials AS CR Brno for calculation of phase diagrams of low melting metals on the base of literature data [1] was used for calculation of surface tension of alloys of these metals. Excess Gibbs energy of liquid phase from the database was taken for calculations by using of our own code exploiting Butler equation [2] for binary systems.
Surface tension of pure metals, necessary for these calculations, were taken from experimental and published measurements performed in the Institute of Metallurgy and Material Science PAS Krakow [3-7]. Comparison of calculated results of surface tension of alloys with experimental ones [3-7] will be presented.
