N2 - A theoretical approach to the explanation of experimentally determined positive enthalpy of formation in Cr-based sigma-phases is presented. It turns out that the energy of formation of sigma-phases in Cr-Co and Cr-Fe systems is found to be negative taking the pure components in sigma-phase structure as the standard states. Our treatment represents a first step to a model of an explanation of the stability of the sigma-phase.
