Název v původním jazyce

Development of New unconventional process of hot stamping

Popis výsledku v původním jazyce

Cold forming of high strength materials is accompanied by an undesirable spring-back effect and therefore the automotive industry prefers to produce components from high strength steels by hot stamping. Hot deformation and cooling in a die are applied toobtain shaped components with martensitic microstructure and high yield strength and ultimate tensile strength. This article presents new applications of this forming technology by incorporating another innovative heat treatment by the Q-P process, which improves both strength and ductility of obtained structures at the same time. Ultimate strengths over 2000 MPa with ductility above 10% can be achieved by this processing. To test microstructure development, thin sheet was hot formed and a corresponding FEM simulation was created. This processing was applied to low alloyed AHS steel with 0.42% of carbon and with an alloying strategy based on Mn, Si and Cr. Martensitic microstructure with retained austenite was obtained by this processi
