Thermodynamic assessment of the Al-Zr binary system

Abstract

The thermodynamic parameters of the Al-Zr binary system can be very useful for the development of Zr-Al based amorphous and nanocrystalline materials. Phase diagram and thermochemistry data, especially the enthalpy of mixing of the liquid phase and the standard enthalpy of formation for the intermetallic compounds, are employed to optimize a consistent thermodynamic description for all the phases. The liquid, fcc, bcc, and hcp phases are treated as disordered solutions, while all the intermetallic phases are taken as stoichiometric compounds. The calculated phase diagram and thermochemistry data agree well with most of the experimental values reported in the literature.
