Abstract

Advanced High Strength Steels (AHSS) were developed for use in the automotive industry due to increasing pressure to reduce vehicle emissions and improve vehicle safety. The AHSS DP600 (commercial name) was the main subject of this study. Dual Phase (DP) steel global formability is comparable to conventional HSS but local formability is poor. Automotive component manufacturing processes require excellent material formability. Uniaxial tensile tests and FLCs are insufficient in evaluating total formability. The Hole Expansion Test (HET) was developed to overcome this issue, it evaluates material stretch flangeability.
