Abstract
A mathematical analysis of the constraints on the thermodynamic parameters of the compound energy formalism for an (A,B)m(A,B)nâ(A,B)m+n type order-disorder transformation is studied. Both the ordered phase and the disordered phase can be described using the two-sublattice model after the formula (AyAâ²ByBâ²)m(Ayaâ³ByBâ³)n, with yiâ²=yiâ³(i=A,B) for the disordered phase and yiâ²â yiâ³ for the ordered phase. The constraints between the parameters for the ordered state were derived. The thermodynamic characteristics of the transformation are illustrated using a mathematical method and the validity of the model and the constraints is tested.
