Abstract : Previously developed computer techniques for calculating phase equilibria between regular solution phases and line compound-regular solution equilibria have been employed to compute binary phase diagrams for twenty titanium base systems including most of the transition metals and aluminum. Comparison with experimentally observed diagrams yields satisfactory agreement. The description includes the activity of each component as well as the heat of formation of compound phases. Extension of this method to ternary and higher order systems should offer substantial advantages in application and development of advanced alloys and composite materials. (Author)
