Thermodynamic assessment of the Al-Zr binary system

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 intermet allic compounds, are employed to optimize a consistent thermodynamic descri ption for all the phases. The liquid, fcc, bcc, and hcp phases are treated as disordered solutions, while all the intermetallic phases are taken as st oichiometric compounds. The calculated phase diagram and thermochemistry da ta agree well with most of the experimental values reported in the literatu re.
