Abstract:
1. A process for making parts from a titanium alloy comprising the steps of: preparing an intermediate form of an alpha-beta titanium alloy wherein said alpha-beta titanium alloy contains not more than 0.0125% hydrogen; then solution heat treating the intermediate form under conditions of temperature and time that are selected to produce a desired level of strength when the alpha-beta titanium alloy is subsequently age hardened; then reheating the intermediate form to an elevated starting temperature of about 1600° F. (871° C.); mechanically working the reheated intermediate form from the elevated starting temperature to a lower finishing temperature not below about 800° F. (427° C.) to provide a desired part or a preform for a desired part; and then, without solution heat treating the as-formed part or preform again, age hardening the as-formed part or preform under conditions of temperature and time that are selected to produce the desired level of strength in said part or preform; wherein after the solution heat treating step and before the mechanical working step the process comprises the step of cutting the intermediate form into pieces having a substantially uniform length.
