Abstract Stable and metastable phase equilibria in Al-Li alloys are investigated using a phenomenological free energy model. In this model, short range order in the solid phases is taken into account within the tetrahedron approximation of the Cluster Variation Method. For the liquid phase, a subregular solution model is used. The energy parameters entering the free energy description of each phase are determined by reproducing selected experimental thermodynamic data and equilibrium… CONTINUE READING
