Formation enthalpies of (001) surfaces terminating ordered Ga_{0.5}In_{0.5}P and GaAs_{0.5}Sb_{0.5} alloys were calculated using the VFF model. For several ordered phases, chemically ordered surfaces were found to be stable against surface segregation. In particular, even phases unstable against bulk segregation may be terminated by a stable surface.
