Reassessment of Ag-Pd System

New CALPHAD assessment of experimental data on phase equilibria and thermodynamic properties of phases in the Ag-Pd binary is performed. The results provide good description of experimental data, excepting one thermodynamic dataset which had to be excluded from calculation due to incompatibility. Results of optimization provides good description of data of phase equilibria, enthalpy of formation and activities of components obtained from 1906 to 2020 in whole range of concentrations and at temperatures from 560 to 1700 K. Differing from the results of published assessment, no artifacts (spurious miscibility gaps) were detected. The value of excess entropy for the composition Ag69.7Pd30.3 obtained from the heat capacity measured from 5 to about 560 K was not included to optimization but was used as independent test of results; the agreement seems to be well within experimental errors.
