Three-dimensional X-ray diffraction imaging of dislocations in polycrystalline metals under tensile loading

Identifying atomic defects during deformation is crucial to understand material response but remains challenging in three dimensions. Here, the authors couple X-ray Bragg coherent diffraction imaging and atomistic simulations to correlate a strain field to a screw dislocation in a single copper grai...
