Thermodynamic investigations on fcc solid ternary Fe-Ni-Cr alloys have been performed by means of the computer-aided Knudsen cell mass spectrometry. Ternary T.A.P.-series (Thermodynamically adapted power series) are used for the algebraic representation of the thermodynamic excess properties. At 1,650 K the molar excess gibbs energy G{sup E} is negative over the whole field of stable fcc phase. The molar heat of mixing H{sup E} is exothermic in the predominant part of the fcc phase field. Only between the section with a constant ratio of mole fraction X{sub Cr}/x{sub Ni} = 0.64 and the fcc phase field boundary the H{sup E} values are slightly endothermic. The results of this work can be used successfully for phase diagram calculations.
