8. Heat treatment

After hot forming and processing, the final touch is to obtain the right microstructure, which determines the final properties:

grain size ;
the distribution and size of the desired precipitates (essentially the hardening phases).

Heat treatment generally consists of three major stages [M 1 165] :

solution heat treatment (950/1,200°C) ;
cooling mode after dissolving: air, oil, water ;
