Abstract

V originále

A thermodynamic database, created for calculating of phase diagrams of low melting metals based on SGTE unary data and binary literature data, was used for calculating the surface tension of binary alloys. The excess Gibbs energy of the liquid phase from the thermnodynamic database was used for calculations using Butler eauation for binary systems. The surface tension and density of pure metals, necessary for these calculations, were taken from published experimental measurements. The computer code for this procedure is presented. A comparison of calculated results with experimental measurements of the surface tension of alloys is given.
