Alveprins Posted April 17, 2016 Share Posted April 17, 2016 Ok, so I wanted to make something a little special... I decided to combine modern #20 steel for the edge, and some - I presumed iron - I'd dug out of the ground on my property which I bought last year. (The oldest part of my house is dated to around 1820) So.. I found this round iron wedge under my old storehouse, along with some chains and farm equipment for digging in the earth and whatnot... So I decided to use the wedge for the san-mai lamination. I drew it out into two flat bars, cleaned them up, and added the modern steel. While working on the forge weld, I noticed the mystery-metal was extremely soft, and it felt as if it would not "take" very well... And by "take", I mean stick to the steel. I found it to be somewhat difficult to get it laminated. The "iron" would simply be squeezed around the carbon steel in the middle - as a result of their quite different levels of hardness obviously. Anyhow, I could see the blade starting to de-laminate even at normalization, so I dropped the differential hardening and just went for a straight quench instead. I got two normalization cycles in before quencing. I let the blade air-cool all the way down to +23C before re-heating. Anyhow, here are some pics: BEFORE QUENCH: AFTER QUENCH: Notice the extreme difference in color between the edge and the jacket? AFTER #120 SANDPAPER: I have no previous experience with iron - so I am asking... Is this how iron looks in contrast to steel in a lamination like this? I thought it looked so special, I could not bring myself to discart the blade. I feel the historical significance of the iron or whatever it is - is too valuable to me to simply discart this otherwise fine blade. The mystery-metal does not even seem to have taken the quench... Hardness is like - less than 40HRC. But the edge on the other hand is as expected 63HRC - which is as high as this particular steel goes. It current rests in my oven at 200C... Oh, and that delamination near the handle area? - I cheated and welded that bastard shut with my arch welder! I'll hapilly take any input and thoughts on that "iron" or whatnot though... I havent seen coloration like that before... Sincerely, Alveprins. Link to comment Share on other sites More sharing options...
