AbstractÐA symmetric two-sublattice model (Ni, Ti, Va) 0.5 (Ni, Ti, Va) 0.5 is applied to describe the intermediate B2 compound in order to cope with the order±disorder transition in the Ti±Ni system. Using this model, the ordered B2 and the disordered Ti-rich b.c.c. are described by a single Gibbs
