Thermodynamic Properties of Binary Gold-Rare Earth Compounds (Au-RE)
Authors: H. Krarchaa, A. Ferroudj
Abstract:
This work presents the results of thermodynamic properties of intermetallic rare earth-gold compounds at different stoichiometric structures. It mentions the existence of the AuRE AuRE2, Au2RE, Au51RE14, Au6RE, Au3RE and Au4RE phases in the majority of Au-RE phase diagrams. It's observed that equiatomic composition is a common compound for all gold rare earth alloys and it has the highest melting temperature. Enthalpies of the formation of studied compounds are calculated based on a new reformulation of Miedema’s model.Keywords: rare earth element, enthalpy of formation, thermodynamic properties, macroscopic model
