Abstract
For High Strength Low Alloy (HSLA) steels or for age-hard enable steels (miraging) the strengthening by precipitation is
done before forming operation to increase the yield stress as much as possible. In this publication the advantages of a hardening
thermal treatment after forming operation are investigated in a low-cost age-hard enable steel Fe-Si-Ti consistent with automotive
application.
