AMS7004A Titanium Alloy Preforms from Plasma Arc Directed Energy Deposition Additive Manufacturing on Substrate, Ti-6Al-4V, Stress Relieved

This specification covers preforms fabricated up through 22.0 inches (560 mm), inclusive, in deposition width thickness (see 2.4) using a wire-fed plasma arc directed energy deposition (PA-DED) additive-manufacturing process on a Ti-6Al-4V substrate that are subjected to post-deposition stress-relief heat treatment. If required by the cognizant engineering organization (CEO), preforms may require subsequent machining to meet requirements for their intended final part application.
