oakwoodforge Posted October 17, 2006 Share Posted October 17, 2006 Water quenched 1080 , In the picture the blue line denotes the quench line , the red denotes the "Odd activity ". This one was not clayed , it was "edge quenched " in Hot , almost boiling water. Any Ideas ? I think It looks pretty cool but I'm wondering what to call this little flame like effect.

oakwoodforge Posted October 17, 2006 Author Share Posted October 17, 2006 I Got an Answer from the "Don" , on this one... "Looks like a vapor jacket formed and slowed down the quench in that area. You can avoid this by agitating the quench or moving the blade. Just a guess -------------------- Don Fogg Don Fogg Custom Knives" Makes sense to me, I'm just glad the blade survived the water quench !!

Lord Farquhar Posted November 10, 2006 Share Posted November 10, 2006 I would go with the vapor jacket but I my would would be that you got a bubble forming under the clay that filled with smoke and stopped the quenchant getting to the blade. Nice blade Quote Link to comment Share on other sites More sharing options...
oakwoodforge Posted November 10, 2006 Author Share Posted November 10, 2006 To clarify, this was a strait water quench, done without clay. My water was much too hot and I did find a soft spot in the edge so I have since annealed, normalized and re heat treated this blade, this time with a clay jacket. After visiting Howard Clark's shop I managed to figure out what I was doing wrong. Now its rainwater or distilled, NOT tap water, and 115 to 120 degrees not 200 degrees. Man quenching in water still gives me the willies though, just dip and just pray you don't hear the Ping-O'- Death. Jens Quote Link to comment Share on other sites More sharing options...
