ABSTRACT

Thermodynamic investigations on liquid ternary Au-Fe-Pd alloys have been performed by means of the computer-aided Knudsen cell mass spectrometry. The "Digital Intensity-Ratio" (DIR) - method has been applied for the determination of the thermodynamic mixing behav-iour. The ternary thermodynamically adapted power (TAP) series concept is used for the al-gebraic representation of the molar excess properties. The corresponding TAP parameters, and the values of the molar excess quantities ZE (Z = Gibbs energy G, heat of mixing H, and entropy S) as well as the thermodynamic activities of all three constituents at 1850 K are pre-sented.
