Microstructure Development in a New Generation S1300‐Type Ultrahigh‐Strength Structural Steel on Tempering Open
Product development routes for new generation ultrahigh‐strength structural steels such as S1300 are currently not well‐defined, warranting studies on their alloy design, processing, and microstructure–property correlations. This study aim…

Influence of Steel Recycling on Phase Transformation in Medium‐Manganese Third‐Generation Advanced High‐Strength Steels Open
Due to the ensuing shift toward adoption of increased levels of scrap during steel production to reduce the carbon footprint, it is essential that the effects of tramp elements entering the produced steel from the scrap are understood. In …

Characterisation and modelling of the flow behaviour of a medium manganese steel for hot forming Open
Medium manganese steels offer a wide range of advantages in hot forming compared to conventional boron steels such as lower heating temperatures and critical quenching rates. Furthermore, the combination of increased strength and ductility…

New Multiphase CP and DP 1000 MPa strength level grades for improved performance after hot forming Open
Pure martensitic steels have after hot forming limited performance in terms of rest ductility which limits the application in crash relevant parts. New steel grades were designed in the EU project HOTFORM including the corresponding proces…
