| Description | Phase equilibria in the Ag-In-Pd system were determined at 500 C based on experimental results for 16 alloys. A ternary intermetallic compound (T1) in the palladium-rich region was confirmed by X-ray diffractometry. The experimental data were first compared with the results of a CALPHAD-type prediction, based on binary thermodynamic data using only a symmetrical Redlich-Kister-Muggianu model. In a second step, the thermodynamic modeling of the different phases in this ternary system was refined by including ternary interactions, and the phase diagram was calculated for the temperature range between 500 and 700 C. With the optimized thermodynamic parameters the phase diagram was extrapolated to 200 C and compared with preliminary experimental results. |
