Thermodynamic assessment of the metastable liquidi in the Al-In, Al-Bi and Al-Pb systems

Abstract

The metastable liquidi in the Al-In, Al-Bi, and Al-Pb systems were assessed through the thermodynamic modelling of the liquid miscibility gaps. The subregular solution model was applied to describe the Gibbs free energy of liquid phases and the interaction parameters were optimized using the phase diagram data. In addition, spinodal curves were assessed to predict the possible regions for metastable phases. The present results were compared and discussed with other experimental and assessed data available from the literature.
