Abstract

The Kaufman approach is combined with values of Δ°H and Δ°S for transformations in pure rare earths to construct phase diagrams for some simple binary systems. Good agreement is obtained for the Dy-Er, Dy-Ho, Tb-Ho and Tb-Er peritectics and for the Ho-Er isomorphous phase diagram. Only limited agreement is attained for the Nd-Pr and Gd-Y double isomorphous systems. The phase diagrams for Sc and the elements Y, Nd, and Gd were least satisfactory. Where agreement is poor, the effects of impurities and other uncertainties are discussed.
