Structure and stability of Laves phases part II—structure type variations in binary and ternary systems
TL;DR: In this article, various models for the prediction of the occurrence and stability of Laves phases have been discussed and the need for careful experimental investigations of phase equilibria is demonstrated, and some general rules for the occurrence of different Laves phase polytypes are derived from a study of the results of experimental phase diagram investigations of various binary and ternary systems.
