“…This suggests, together with the fact that the diffusion distance is of a very short range, that this kind of process should take place at very low temperatures, being highly exothermic. This is in agreement with experimental indications [36], which point to temperatures lower than 140 8C for the start of the first Other results indicate that recovery and in particular reordering take place very quickly during annealing [37].…”

In this work (part 1 of 2), we used the embedded atom method (EAM) to perform atomistic simulations in the molecular statics framework, aiming to investigate the interactions between point defects (both vacancies and antisite atoms) in Fe-Al alloys. This method is particularly useful in obtaining the self-energies of crystal defects characterized by strong core relaxation strains, which generate long-range elastic fields. The following cases are considered: divacancies, vacancy-antisite and antisite-antisite atom pairs in Fe (A2), FeAl (B2) and Fe 3 Al (D0 3 ) compounds. In each case the most stable configuration has been found and the dependence of the interactions of these pairs of defects on their separation distance has been investigated. Particular care was taken to ensure that all simulations for a given compound are performed in the canonical ensemble. q
