Using a novel visualization tool for 3D reconstruction and visualization of dislocation line segments from stereo-pairs of scanning transmission electron microscopies, the superdislocation substructures in Ni-base superalloy LEK 94 (crept to ε = 26\%) are characterized. Probable scenarios are discussed, how these dislocation substructures form.}, language = {en} }
