“…Recently, Wasiur-Rahman and Medraj [36] reoptimized the Al-Zn system with MQM. The thermodynamic descriptions of Al-Zn system reported by Mey [33] was used to establish the thermodynamic databases for the Al-Mg-Zn [37], Al-Cu-Zn [38], and Al-Zn-Ti [39] systems. In consideration of the compatibility of thermodynamic database in multicomponent systems, the thermodynamic parameters of the Al-Zn system from Mey [33] were adopted in the present work, while the Sn-Zn binary system was thermodynamically assessed by several other authors [40][41][42].…”

In this paper, a thermodynamic re-assessment of the Al-Sn-Zn ternary system was performed by means of the CALculation of PHAse Diagram (CALPHAD) approach. The thermodynamic descriptions of the binary Al-Sn, Al-Zn, and Sn-Zn systems from the literature were directly adopted, and the newly reported experimental phase equilibria, enthalpies of mixing, and activities of Al in the ternary liquid phase were taken into account. A set of self-consistent thermodynamic parameters for the ternary Al-Sn-Zn system were finally obtained. A comprehensive comparison between the presently calculated phase equilibria/thermodynamic properties and the experimental data indicates that the present thermodynamic descriptions of the ternary Al-Sn-Zn system show very good agreement with most of the experimental data. The further direct comparison with the calculated results due to the previous assessment demonstrates that a significant improvement was achieved by the present assessment though fewer ternary interaction parameters were utilized.
