Thermodynamic evaluation of the Au-Bi system

Résumé

Available experimental information concerning thermodynamic properties as well as phase equilibria data have been compiled for assessment of new self-consistent parameters of thermodynamic models for all phases in the Au-Bi system. These coefficients have been optimized by using a program developed by Lukas et al. Calphad, 1 (1977) 225. Phase diagram and characteristic thermodynamic functions have been prepared, and compared with the experimental values from the THERMODATA software. Very satisfactory agreement was obtained by using eleven optimized coefficients, with a simple substitutional model for the liquid and fcc phases and either a linear approximation or a three terms expression for the temperature dependency of the Gibbs energy of the stoichiometric compound Au2Bi.
