... of nearly 86% alpha phase. However, the small amount of beta phase is extremely rich in vanadium content (nearly 16%), while the vanadium content in the alpha phase is similar to that of the binary Ti-4V. In summary, the addition of an alpha stabilizer to a binary beta-stabilized alloy results...

..., chromium, silicon, iron, cobalt, nickel, and copper. Finally, tin and zirconium are considered neutral because they neither raise nor lower the beta transus temperature, but since both contribute to solid-solution strengthening, they are frequently used as alloy additions.

... and growing on certain preferred crystallographic planes of the parent beta phase. The Widmanstätten structure can be produced in beta-lean alloys by using intermediate cooling rates from the beta field. In alpha-beta alloys, where the beta phase is rich in solute (beta-stabilizing elements), some beta...

... of variations in the interstitial and impurity levels. Alpha alloys that contain aluminum, tin, and/or zirconium are preferred for high-temperature, as well as cryogenic applications. Alpha-rich alloys generally are more resistant to creep at high temperature than α-β or β-alloys. The extra-low-interstitial...
