This study shows that energy-resolved neutron imaging can be used to non-destructively characterize the microstructure of nickel-based superalloys, by providing maps of the spatial distribution of lattice parameters, misfit and misorientations of the γ and γ′ phases with a spatial resolution of ∼500 × 500 µm.
