PROCESSING OF ALPHA/BETA TITANIUM ALLOYS

摘要

Processes for forming an article from an α+β titanium alloy are disclosed. The α+β titanium alloy includes, in weight percentages, from 2.90 to 5.00 aluminum, from 2.00 to 3.00 vanadium, from 0.40 to 2.00 iron, and from 0.10 to 0.30 oxygen. The α+β titanium alloy is cold worked at a temperature in the range of ambient temperature to 500° F., and then aged at a temperature in the range of 700° F. to 1200° F.
