The annealing process involves heating to 480C for 6 h and stepping down to 420C for 2 h, to evolve a microstructure with good mechanical properties that will enhance material formability. This study presents an appropriate heat treatment procedure that depends on crystal ordering and on the chemistry of the alloy.
