Abstract

The Al-Fe system is important in many alloys and the new interest in iron aluminides makes it necessary to improve the modelling of the different ordered forms of the A2 lattice in this system. This has now been done using a 4 sublattice model based o the Compound Energy Formalism (CEF) which can describe B2, D0 3 and B32 ordering. The ordering transition can be both first and second order and the ferromagnetic ordering has also a critical influence. All experimental data have been fitted within estimated uncertainties.
