Summary: | For a long time the Cluster Variation Method (CVM) has been used for modelling the configurational entropy of phases with order/disorder transformations. Recently this model was implemented in more general software for phase-diagram calculations and one could take advantage of the extensive facilities offered by this software to explore the model. An irregularity in the configurational heat capacity around the ideal ordering compositions was then discovered. The reason for this behaviour is discussed and also whether it is model-dependent. |
