    Materials science is pretty amazing. You actually get different metal characteristics based on how something is cooled, at what temperature it’s heated, and how quickly it’s cooled.

      Yep. Seen the same part be almost impossible to mill with TiC bits, annealed for like 30min and then it curls chips like no tomorrow. Re-quench and carbide again bounces off.

      Wild.

    Ideally the whole thing is submerged all at once to reduce stress inside the steel. It obviously gets more difficult the larger the part is.

    Is oil used because water would evaporate away too quickly?

      The Leidenfrost effect might just keep them apart and prevent heat transfer.
