Comparison of phase contrast (PCT) and diffraction contrast tomography (DCT) reconstructions of an austenitic–ferritic dual-phase steel. (a) PCT reconstruction; (b) DCT reconstruction of the austenite phase; (c) DCT reconstruction of the ferrite phase. The PCT reconstruction provides higher accuracy but weak contrast in the grain boundaries. The DCT reconstruction segments the phases and measures grain orientations.
