I am really glad to see Sandia using PR3D. For a few years now Sandia has been trying out seemingly everything else other than PR3D. But something changed, because this test matrix was for one of the most important characteristics of metal AM. Charpy testing is a method to indicate material toughness. It encompasses basically everything intrinsic to metal behavior in doing so. You can't have high toughness if any of the individual metal parameters is poor.
It looks to me as though Sandia was using TED to set three largely different energy flux conditions so they could see how Charpy behaved in the different energy bands. It also looks like they were looking to see if TED could predict Charpy. TED tracked density, and density tracked Charpy. So TED indirectly tracked Charpy.
Pretty good stuff.
I don't see where Honeywell comes in with this though. Am I missing something?
All the best,
Silversmith
