A thermodynamic description of the Ni–Al–Cr–Re system

Abstract

Thermodynamic properties of the Ni–Re binary system were analyzed using thermodynamic models for the Gibbs energy of individual phases of the system. The model parameters were optimized from limited experimental phase equilibrium data and estimated thermochemical data. Thermodynamic descriptions of the Ni–Al–Re and Al–Cr–Re were also discussed. A thermodynamic description of the Ni–Al–Cr–Re quaternary system was obtained by combining consistent thermodynamic descriptions of its lower-order systems. The calculations using these thermodynamic descriptions show good agreement with available experimental data of both the Ni–Al–Re and Ni–Al–Cr–Re systems.
