Titanium Alloy Preforms from Plasma Arc Directed Energy Deposition Additive Manufacturing on Substrate Ti-6Al-4V Stress Relieved
Published January 31, 2019 by SAE International in United States
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.

* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
