    Alloy Design
    Invited Lecture

    The development of new advanced high-strength steels is traditionally a very tedious process, involving extensive experimental investigations by which composition and processing conditions are varied in a more or less erratic manner until the desired properties are achieved. This situation has a tremendous negative impact on alloy development time and costs. The Alloyneering alloy design...

    Failure, Damage and Hydrogen
    Oral Presentation

    Hydrogen embrittlement (HE) is a persistent mode of failure in high-strength steels
    which hinders their applicability in industry. The role of retained austenite (RA) in the
    HE susceptibility of these steels is still unclear. There are two possible scenarios, firstly
    since the solubility of H in austenite is remarkably larger than that of martensite, the
    RA phase can act as a trap for H...

    Microstructure-Properties relationships
    Oral Presentation

    In the present work, a metastable Cr-Mn-Ni steel with deformation-induced plasticity was investigated. The influence of martensite formation on the mechanical properties of an Fe-16Cr-6Ni-6Mn (concentrations in wt-%) austenitic stainless steel was studied by tensile tests between -70°C and 300°C. As-quenched martensite formation was observed at temperatures below -30°C. Deformation-induced α'...

    Modelling and Simulation
    Oral Presentation

    Excellent combinations of strength and ductility have been observed in complex phase medium Mn steels, due to the activation of TRIP and TWIP in retained austenite, stabilized at room temperature via C and Mn partitioning. Limited attempts have been made in the past to model the deformation behavior and transformation kinetics of medium Mn steels. Previous studies relied on fitting the...

    Modelling and Simulation
    Oral Presentation

    High manganese steels are considered to be promising alloys for light weight applications due to their high strength and good ductility based on their special microstructure. During plastic deformation the mechanisms of twinning induced plasticity (TWIP) and transformation induced plasticity (TRIP) lead to a strong microstructure refinement within the material. Previous studies have shown that...

    Heat treatment and Phase transformations
    Oral Presentation

    To control the production processes and design product properties of promising medium and high Mn steels, reliable solidification and material models are essential. High precision and experimentally validated thermodynamic data are essential data sources for all these models. As manganese is a segregating element, it is crucial to describe high manganese concentrations well, e.g. for the final...
