I watched some footage of an old gun HT method I thought was pretty neat. They pack the steel in a container with Charcoal and Bone. After packing they place it in furnace, forge or what have you. and heat it to I believe 1200 degrees. Same tempurature as lava from a volcano, nearly at melting point then quench it. The steel gets so hot that it pulls Carbon from the Charcoal and bone.
There are warpage issues and I'm not certain how it would land on the HRC BUT Could this HT method be applied to knives? appling this to a damascus blade may be interesting!
Some of our more scientific makers/crafstmen/metallurgist may be able to shed some light on this. How it may effect the steels composition and characteristics. If this is something that has not been widely done in regards to knives, maybe DT, BB, Butch, pierre or someone may be willing to give a petty knife a shot.
Would it stengthen ware resistance?
Would it be to Hard, possibly to brittle?
Would the fact that it draws out carbon from it's environment during Tempuring alter the composition in an unworkable or unpredictable manner?
Just something thats been rolling around in my head lately..
