摘要
Knudsen cell mass spectrometry has been employed to investigate thermodynamically the fee solid ternary Fe-Ni-Co alloys over the entire range of composition. The "Digital Intensity-Ratio" method has been applied for the determination of the thermodynamic excess properties. The values of the molar excess Gibbs energies G(E), the molar heats of mixing H-E, the molar excess entropies S-E, as well as the thermodynamic activities at 1600 K are presented.
