Engineers invented metals that can remember their shape after being dented. The atoms are packed into groups of different sizes. According to the engineers the metal does not matter, what matters is the grains in the micro structure and the size of the grouped atoms. The grains have to be brittle but not too bendy. After a disfiguring the atom grains let out energy that force other grains back to their original position. It be would be great if the metals are used in cars. It would mean no more expensive repairs on fenders.
