A thermodynamic evaluation of the Au-Sb and Au-Tl systems
Résumé
The two binary systems Au-Sb and Au-Tl have been thermodynamically assessed in the framework of a long term programme to provide thermodynamic databases in order to perform calculations in multi-component systems. for each of these systems, two different sets of self-consistent parameters have been obtained by using the optimization procedure developed by Lukas et al. (Calphad, 6 (1977) 225). phase diagram and characteristic thermodynamic functions have been calculated and compared with the corresponding experimental values using the THERMODATA software. The reasons why a definitive set of coefficients cannot yet be selected for the two systems are discussed, and proposals for further experimental work are given in order to conclude that work.
