This specification covers preforms fabricated up through 5.5 inches (140 mm) inclusive in deposition width thickness (see 8.2.5) using a 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. This is a wire fed additive manufacturing process. If required by the CEO, preforms may require subsequent machining to meet requirements for their intended final part application. This is an initial release specification for titanium alloy preform made using plasma arc directed energy deposition additive manufacturing process.
