Steve - I've annealed hardened drill couplers by heating them to orange where you just get little sparks leap off the surface and them bury them in a bucket of ash and let them cool slowly.
I'm sure there is a more technical procedure but that is what worked for me. Then again, they were used for nothing more than scrap metal to practice with. With what you want to do, the oxidation will need to be limited and I'm unsure of the steps required.
So - come to think about it - this probably isn't any help at all
