Critical assessment of iron binary systems with light rare earths La, Ce, Pr, and Nd

Literature data regarding phase equilibria and crystal structure data in the R–Fe systems with R = La, Ce, Pr, Nd have been assessed and the corresponding phase diagrams are presented and discussed. Selected investigations on other constitutive properties (such as magnetic, electronic, thermodynamic) of the R–Fe alloys are also briefly reported. to the numerous investigations some uncertainties remain in the R–Fe phase diagrams and further investigations would be useful.
