A new EBSD based methodology for the quantitative characterisation of microstructures formed by displacive fcc-bcc transformations

► New methodology for quantification of packet formation in steel and weld microstructures. ► Representation of misorientation distribution in Rodrigues-Frank space. ► Habit plane of displacive transformation products verified using EBSD data. ► Using the misorientation distribution to split the grain boundary network into inter- and intra-packet classes.
