Contribution to the evaluation of rare earth alloy systems

  • Published:
Journal of Phase Equilibria

Abstract

It is well known that within the family of the rare earth elements (especially the “trivalent” ones) several properties change according to well-recognized and systematic patterns. A general consideration of the constitutional properties (thermodynamic properties, crystal structures, and phase diagrams) of alloys formed by the various rare earths enables a number of empirical regularities to be deduced. This behavior can constitute a prediction scheme and a reliability criterion in the evaluation of the data concerning series of various rare earth alloys with the same element. Examples of the application of this behavior to phase diagram assessment and prediction are mentioned. Special attention is given to the binary rare earth alloys formed with magnesium and aluminum. The predicted versions of the Tb-Mg and Tb-Al phase diagrams are presented at the end.
