Abstract: Current hot stamped steels can offer ultra high strength (1500 MPa) with limited elongation (∼5%). Research is ongoing to develop hot stamped steels with similar strength and improved ductility by using various microstructural approaches. The current work describes in depth the characterisation of microstructural features of a steel that was processed via a quenching and partitioning method in a modified hot stamping thermal cycle to deliver a good combination of strength and ductility. It was found that the microstructure thus produced is very complex comprising many different phases. As it is also beyond the ability of one single technique to fully characterise it, several techniques were employed in order to properly understand the various features of the different constituents of this microstructure. © 2017 Institute of Materials, Minerals and Mining.
