Understanding phase transformations in steels using modern electron microscopy techniques

The advantages and limitations of electron back-scattering diffraction coupled with energy dispersive X-ray spectroscopy and of transmission Kikuchi diffraction in relation to the in-depth characterisation of steel microstructures containing phases with similar lattice parameters and/or precipitates are discussed. An in-house developed EBSD map post-processing methodology provided insights into the mechanisms of bainite formation.
