Abstrakt: A stability analysis of classical binary bcc superstructures with one or two long-range order parameters is performed. The feasibility criteria for ordered phases formulated for fcc superstructures are found to apply to bcc superstructures. The feasibility criteria assume that the ordering energy in the first coordination sphere is positive, and the energy range in interaction space where bcc superstructures are stable (stability range) is unlimited.
