| Abstract Scope |
Modeling the gamma gamma prime equilibria i.e. the thermodynamics of the Ni based fcc solid solution and its ordered variant based on the Ni3Al compound is of tremendous interest in the aircraft engine framework. Starting from the stoichiometric model of the gamma prime introduced in the seventies, improvements of the empirical Calphad models and their application to a large number of systems have allowed to develop commercial databases describing reasonably well phase equilibria in the industrial alloys. The recent implementation of the Effective Bond Energy Formalism opens to multi-component databases that will be faster, closer to the crystallography of the phase, more physically based and provide higher quality results. |
