Amazing! Sorry, Chuck! :(
Just curious at what they look like where the split is. And what are you gonna do with them?
What I was meaning was the sides of were the 2 pieces used to meet. Its probably nothing to see. You only have a pic. from the top.
OK that is what i was thing but wasn't sure. looks like a nice fine grained break. I'll see if I can get a picture.
DANG!!!! I tried welding up 416 and Cru Forge and it just never stuck, but that is funky the away the core split. I think I recall one of the guys who does that a lot saying that you might want to clay up the spine on those laminates because the do get stressed all to hell in the quench. Derrick Wulf made a san mai blade recently using 304 as the cladding instead of 416 and he says it welds a lot easier. It also isn't martensitic steel , so I wonder if it gets stressed out less.
The fact that it crack is so symmetrical is really interesting. It seems improbable the the stresses would be so balanced and that the core steel would be the weaker element. As far as I'm concerned, this is an endorsement of your method (ignoring the obvious), that you can create something so balanced.
When I first started doing this laminate in 2002 I was talking with Daryl Myer and was told by him that this could and would happen. According to Daryl it is far more likely to happen with 300 series stainles than with the 400 series that I use and the reason that I use it in the first place. For those of you who don't know who Daryl Myer is Pretty much every modern pattern welding technique that we use in some way belongs to Daryl.
I think you have a great piece of modern art there.
Now you just have to figure how you will display your new sculpture.
