The Action created the scientific platform needed for the development of new alloys based on intermetallic compounds. It was based on the modelling of the thermodynamic properties of engineering aluminides, evaluating existing data and acquiring new data, based on theoretical and experimental approaches. It required interdisciplinary efforts from experimentalists, physicists and metallurgists (i.e. materials scientists). The modelling approaches were supported by intense experimental studies of thermodynamic and physical properties of the individual phases, as well as of phase equilibria. The Action used two different approaches. The first was the development of the broadest possible set of semi-empirical consistent Gibbs energy models for alloy systems containing aluminides, with the Al-Fe-Ni-Ti system as a core and the second was an increase in the understanding of aluminides themselves and how they interact with chosen alloying elements.The result was the database, developed with emphasis on its accuracy concerning the core Al-Fe-Ni-Ti system as well as to its capability in relation to further additions.
