We have investigated the correlation between the bond energies used in a nearest-neighbour mean-field model and the point-defect behaviour. We have identified four broad types of behaviour that could be exhibited by B2 intermetallics with respect to the variation in vacancy concentration with alloy composition. Our results show that alloys would exhibit constitutional vacancies for a wide range of bond energy combinations. Using a bond-breaking model, we have identified the condition on the bond energies for which the alloy would exhibit constitutional vacancies. Finally, we have rationalized the different mean-field results in the literature for \beta -NiA1 in terms of the bond energies used in those studies.
