A general correlation between the phase stability and the elastic properties in beta(body-centered cubic)-type Ti-alloys is investigated with the aid of two electronic parameters. The extent of the single P-phase field is clearly represented using these parameters. It is also shown that the addition of Al, O, and Sn is effective in modifying greatly the stability of the P-phase, because they work as the beta-stabilizing elements in these P-type alloys, resulting in significant changes in the elastic properties of alloys.
