    Advances in Steels for Stronger Body in White and Enhanced Safety
    Anthony J DeArdo
    University of Pittsburgh

    ABSTRACT
    Over the past quarter century, the crashworthiness of production automobiles has improved significantly. sa Much of this improvement is the result of application of ultra-high strength steels in the safety cage or Body in White. Since the majority of steel mass resides in...

    Steel materials and their application
    Oral Presentation

    Nowadays the use of scrap-based Electric Arc Furnace (EAF) steels is a reasonable solution to reduce CO2 emissions, as the availability of steel scrap is expected to increase in the next 10-20 years. However, CO2 reduced steel produced with an EAF contains a higher amount of tramp elements such as copper and nickel compared to material from primary steel making. As one task in the material...

    Dual phase (DP) steels, consisting of a soft ferrite matrix and hard martensite phases, offer a desirable combination of high strength and good ductility. Typically, an increase in martensite phase-fraction leads to higher strength but reduced ductility. However, in this study, an opposite trend was observed, where the ductility improved despite an increase in martensite content. This study...

    Steel materials and their application
    Oral Presentation

    new production routes. Different scenarios for the substitution of gas-fired furnace with electrical powered solutions can be considered. In particular, flash annealing – so far only considered at laboratory scale – can be introduced at industrial level providing substantial benefits in terms of productivity and material properties.
    The beneficial effect of flash annealing on the material...
