A little Wip for some techniques I have picked up in san mai. And an experiment in 01/damascus to make a blade for testing and comparison.
First making some simple damascus in 75ni8/en42J
The billet welded up, I now use the fullers in the power hammer to manipulate the layers, a sort of forged ladder effect, there is a thickening and thinning of the layers that remains after flattening.
Cut to 4 and restack, back in the fire.
Some slightly sharper fuller tools
Can see the cool grain in the damascus
Damascus billet
San mai'd with mild steel. The ratio is important, depending on how close you want the san mai, the type of grind etc. The mild will thin quicker than the core and this needs to be allowed for.
I fullered the san mai together as well, to achieve a ripple effect on the weld line.
Plenty of stock, quite an efficient use of damascus.
Ratio after forging
I got an extra one out of the left over damascus too. This one had the damascus as the cladding and 01 in the middle. I've been looking at the temper temperatures and I think these will work well together. At a 200*c temper I should have something like 62hrc on the core and 52ish hrc on the damascus cladding. Sounds good to me
