Description
A method was developed to automatically recognize the orientations of primary αp grains and secondary αs colonies of a bimodal titanium alloy, on the orientation map. Both populations of grains are dissociated by correlating the Electron Back Scattering Diffraction data with the corresponding Back Scattered Electron image on which a high chemical contrast is observed between the αp and (αs+βresidual) phases. The whole data processing is successfully applied to a large EBSD map of a bimodal IMI 834 billet. This allows to discuss the contribution of αp grains and αs colonies to the sharp texture heterogeneities observed in the billet
