I used to look after a salt bath heat treatment setup during the war. Twenty minutes in molten salt at 490/500 C followed by a water quench. After 2 hours, dural re-crystallises and has to be heat treated again for further bending. We called it 'normalising' but more correctly it was 'solution treatment'. O.T.
