Patent ID: 8048240

Claim:
A method of forming an article from an α−β titanium alloy consisting of, in weight percentages, from 2.9 to 5.0 aluminum, from 2.0 to 3.0 vanadium, from 0.4 to 2.0 iron, from 0.2 to 0.3 oxygen, from 0.005 to 0.3 carbon, from 0.001 to 0.02 nitrogen, from 0 to 0.1 chromium, from 0 to 0.1 nickel, incidental impurities, and titanium, the method consisting of: α−β working the α−β titanium alloy at a temperature greater than 1600° F. to provide the α−β titanium alloy with a microstructure conducive to subsequent cold deformation; and cold working the α−β titanium alloy at a temperature in the range of ambient temperature to less than 1250° F.; wherein the article has tensile strength of at least 120 ksi and ultimate tensile strength of at least 130 ksi.
