Determination of Material and Process Characteristics for Hot Stamping Processes of Quenchenable Ultra High Strength Steels with Respect to a FE-based Process Design 2008-01-0853

For lightweight construction, besides the conventional lightweight materials like aluminium and magnesium, ultra high strength steels are being increasingly used in the automotive industry. For example the quenchenable ultra high strength steel 22MnB5 is applied for the production of complex crash relevant components. The processing of the boron micro-alloyed steel 22MnB5 is carried out in an innovative, non-isothermal hot sheet metal forming process, which combines forming and quenching in one process step. The process itself as well as the experimental determination of relevant process parameters like thermal and mechanical material properties with respect to a more reliable numerical process design will be introduced and explained.
