Gary Mulkey Posted October 4, 2010 Share Posted October 4, 2010 (edited) I ran into something that is beyond me to answer and hopefully one of you can help. I recently heat treated a damascus blade that warped when quenched (Park's 50). When I put it in the oven to temper, it relaxed and straightened which would indicate to me that it had cooled unevenly when quenched. (I had quenched it in a 5 gallon bucket of Park's 50 and adgitated it sideways.) Normally when a blade warps on me I expect it to be unevenly ground but this one seems to be a equal left/right grind. I can understand why a damascus blade might warp but not why it would straighten on tempering. Any ideas why a blade would warp when quenched & straighten when tempered other than possible uneven cooling when quenched?
