Hey everyone! I thought I would share my latest failure, because ... well because there's always something to learn from failure. Besides, I'm still somewhat pleased about this blade, and I wanted to share. This all started when I decided to slice a piece of Campo Del Cielo meteorite, a fairly common iron-nickel meteorite, with your typical widmanstatten and neumann bands, kamacite, taenite, plessite, and the odd troilite inclusion (Group I: 6.68% Ni, 0.43% Co, 0.25% P, 87 ppm Ga, 407 ppm Ge, 3.6 ppm Ir) Cutting that ended up ruining a
Not sure if this is the correct place to post this, but it seemed like a good idea at the time. I found this link while surfing and it has some interesting stuff and a couple of videos. Thought someone would enjoy them, and maybe start a conversation. http://www.cnet.com/pictures/swords-from-the-stars-weapons-forged-from-meteoric-iron/?ftag=ACQf1069b9
So first, a little set-up for context: I'm working a bar of damascus, composed of W2 and Iron meteorite (campo de ciello) which is iron with ~6% nickel and a sprinkling of other stuff. The billet is about 2:1 tool steel to iron, with a desired distribution of about 60 points of carbon. After forging and welding up to a 32-layer stack, a sample was cut, further forged into a blade, and quenched in warm oil (5 minute soak at 1450). The iron in this sample had been at near-welding temperatures for almost 2 hours alongside the W2, yet remained soft after the quench. So here's my curiosity.
