A full thermodynamic optimization of the Zn-Fe-Al system within the 420-500 ∘C temperature range

By comparing calculated quantities and their experimental counterparts, it was demonstrated that the thermodynamic model proposed for the Zn-Fe-Al system could be relied upon within the 420-500 ∘C range, i.e. within the region important for galvanizing and galvannealing. It is difficult to speculate whether the model remains workable outside this temperature interval since almost all experimental data reported in literature were obtained within the limits specified.
