SUMMARY
Three Fe-Er, Fe-Lu, and Fe-Y binary systems were reassessed through the CALPHAD method in the
present work according to the reliable experimental results and the earlier calculations in the literature. An
improvement to our previous assessments of the Fe-Tb and Fe-Dy binary systems was obtained by revising
the expressions of the Gibbs energies of Fe Tb and Fe Dy and thus eliminating the artificial break in their
