We can melt an alloy and when it hardens, it can re-shape itself back into it's original shape??????
If it exists it would be a Titanium Alloy!
The Naval Weapons Research Laboratory discovered Nitinol when they made small alloy sample for hardness testing.
They punched a dent into a metal cylinder test sample and put it on the windowsill and went to have lunch.
After they came back the Sun had heated up the samples and the Nitinol ones had no dents!
The dents had erased themselves!
And so began the Memory Metal story!
And you may own eyeglass frames may be made of these Memory Metals or Shape Memory Alloy.
I do not use Titanium frames cause they are too expensive and they do not last any longer than stainless steel.
I get my frames cheap at Costco.
