Abstract
This study presents the results of experimental and analytical tests. Experimental part includes results of the hardness and electrical properties of the selected ternary Ag-Ge-Sn alloys. In the experimental part of the study, alloys of selected compositions were prepared and then examined using scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS), X-ray powder diffraction (XRD), hardness measurements by Brinell method and electrical conductivity measurements. Analytical part includes, calculations of equilibrium phase diagram of the Ag-Ge-Sn ternary system by using the Calphad method and the corresponding thermodynamic program (Pandat ver. 8.1). The results include calculated characteristic isothermal sections. Isothermal section of the ternary Ag-Ge-Sn system at 25 °C have been extrapolated using optimized thermodynamic parameters from literature. Experimentally obtained results were compared with the results of thermodynamic calculation of phase diagrams. Good overall agreement between experimental and calculated values was obtained. Hardness and electrical conductivity of selected alloys were measured and by using appropriated mathematical model these properties were predicted in
the whole composition range.
