Abstract
The order-disorder transition in hcp binary alloys is investigated by Monte Carlo simulations and the renormalization-group methods. The inclusion of the interactions beyond the nearest neighbors induces quantative changes of the phase boundaries. Especially, the contribution from second-neighbor in teractions explains the shift along the concentration axis of the congruent point of order-disorder transition observed in the alpha/alpha(2) phase bo undaries in the Ti-Al binary system.
