Steel&Hydrogen - POSTER - Fracture resistance and local formability of advanced high strength steels in presence of hydrogen

The research and development of the 3rd Generation Advanced High Strength Steels is focused on the improvement of their formability without significant sacrifice of strength. However, these 3rd Gen AHSS are still under development and the effect of hydrogen on the steel formability must be well understood. In this work, the influence of H content on the formability and fracture resistance of CP 1200 is assessed by means of Hole Expansion Tests and the Essential Work of Fracture methodology,
