Thank you Mike. To my knowledge this will be the first (modern) technical analysis of a pattern welded barrel failure, and should be the makins' of a good article for DGJ. I'll ask the METL engineer for good images of the testing process and SEM results.

I would very much like to compare the composition of a low grade Belgian Twist, mid-grade Damascus, and high grade Damascus barrel using EDX.
