| Summary: | The thermodynamic properties and characteristic phase diagrams of some sections in the Ag-Bi-Sn system were calculated. The thermodynamic functions, such as Gibbs excess energy, activity and enthalpy of formation, were calculated using the RKM model and compared with experimental data reported in the literature. Iso-activity diagrams for all three components at 900 K have been constructed. The calculated phase diagrams of the vertical sections Sn-AgBi, Ag-BiSn and Bi-AgSn, obtained using the ThermoCalc program, were compared and confirmed with the results of DTA measurements from the present work. . |
