Abstract

This work presents the results of the thermodynamic optimizations of several Au-RE (RE = Ce, Nd, Sm, Eu, Gd, Tb, Dy and Yb) binary phase diagrams using the CALPHAD approach [D. Moustaine, K. Mahdouk, J. Alloys Comp. 683, 599 (2016); 673, 115 (2016); S. Otmani, K. Mahdouk, J. Alloys Comp. 670, 369 (2016); 648, 581 (2015)]. We compare and discuss, in this study, the alloying behavior as well as the evolution of multiple thermodynamic data relative to the Au-RE phases versus the atomic number of the RE element.
