Abstract
An alpha-beta titanium-base alloy having a good combination of strength and ductility with a relatively low cost composition. The composition, in percent by weight, is 5.5 to 6.5 aluminum, 1.5 to 2.2 iron, 0.07 to 0.13 silicon and balance titanium. The alloy may have oxygen restricted in an amount up to 0.25%. The alloy may be hot-worked solely at a temperature above the beta transus temperature of the alloy to result in low-cost processing with improved product yields. The hot-working may include forging, which may be conducted at a temperature of 25.degree. to 450.degree. F. above the beta transus temperature of the alloy. The hot-working may also include hot-rolling, which also may be conducted at a temperature of 25.degree. to 450.degree. F. above the beta transus temperature of the alloy.
