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. Owing to the numerous investigations some uncertainties remain in the R-Fe phase diagrams and further investigations would be useful. (C) 2008 Elsevier B.V. All rights reserved.
