Dislocation Density Mapping in 3D

Through this proposal, we aim to map the full dislocation density tensor field by recording 3 independent reflections using Dark Field X-ray Microscopy (DFXM). These high-resolution experimental maps will be integrated into state-of-the-art Continuum Dislocation Dynamics (CDD) models to address critical materials science questions. The insights gained will guide the development of improved numerical models and resolves long standing challenges in the understanding of dislocation dynamics.
