Geometrical necessary dislocation densities can be measured via HR-EBSD through cross-correlation of Kikuchi patterns
Plastic deformations of structural materials at the microstructural level are often heterogeneous. Here, we used SEM-based techniques, e.g. HR-EBSD, HR-DIC, and micro-grid methods, to identify the favourable microstructural features for strain accumulation. Together with nanomechanical tests, we will be able to provide a more complete description of deformation mechanics of structural materials (deformation & mechanical properties)
