Abstract
A predominately .alpha.-phase titanium base alloy having good high temperature creep strength. The alloy has about 8% aluminum to promote a strengthening .alpha..sub.2 precipitate, and about 5% columbium to ductilize the .alpha..sub.2 precipitate. Additionally, the alloy has about 5% zirconium, up to 0.5% silicon, up to 2% tin, and up to about 1.5% molybdenum.
