V originále
In lead-free soldering, the silver is usually used as solder component and palladium often as component of substrate. Therefore, Ag-Pd system is of interest for possible interference of components in solder joints. The system Ag-Pd reveals simple liquidus-solidus two phase region [1]. An enthalpy of mixing of liquid Ag-Pd solution was evaluated recently [2]. In this work an additional DSC determination of solidus and liquidus temperatures at chosen compositions was performed. Existing assessment [1] of thermodynamic and phase equilibrium data in the Ag-Pd system was revised on the base of calorimetric data for liquid Ag-Pd alloys [2] and DSC measurement. New determination of liquidus and solidus temperatures using DSC method in this work confirmed substantially narrower liquid/fcc two-phase field in phase diagram, in agreement with the reassessment.
