If I bend a piece of metal forward and back a bunch of times, eventually it will break even if I couldn’t break it in the beginning. I believe that is due to metal fatigue(?) How does that work? What’s specifically getting “tired”? the chemical bonds? the structural integrity?
Say I have a piece of metal that I bent and unbent thousands of times. If I melt it back and recreate the shape, does the fatigue “go away”? How does it work?
