Can someone help me explain how a plate of metal's yield strength changes as it is 1) Rolled (flattened) then 2) Heated for some hours and cooled, and then finally 3) Cooled and rolled additionally.(adsbygoogle = window.adsbygoogle || []).push({});

Does the yield strength increase at first, then drop, and then increase again? That's what I think, but I'm not sure. And if so, can someone please explain to me why this happens? Thank you. :shy:
