Abstract
The relative stability of phases in driven systems such as alloys under irradiation cannot be assessed from thermodynamic potentials. Nevertheless, starting from a mesoscopic stochastic description, one can define a potential which governs the probability distribution of macrovariables (for instance the composition and order parameters). As examples, we recall here the results obtained, in the simplest mean-field approximation, for order-disorder transitions on the BCC lattice (B2 ordered phase) and on the FCC lattice (L12, L10, D1a, LiFeO2-type ordered phases). Inversion of phase stability, occurrence of tricritical lines, sensitivity of phase boundaries to “cascade size effect” are predicted.
