Quenching and Partitioning (Q&P) steels offer an excellent combination of strength and ductility. However, the crystallographic nature of phases and the mechanisms of austenite carbon enrichment involved in Q&P steels are still not well established. From in-situ High Energy X-Ray Diffraction experiments throughout the whole Q&P treatment, coupled with image analysis, Transmission Electron Microscopy and modeling at phases scale, we give some clarifications regarding: - the nature and the structure of phases, - the kinetics of phase transformations for different process parameters, - the mechanisms of carbon enrichment in austenite and more particularly the complex interactions between carbon partitioning from martensite, bainite transformation and carbides precipitation are analyzed.
