Preview Abstract
The nanoscale deformation field of twin boundary dislocations in nanocrystalline aluminum was experimentally investigated using a combination of high-resolution transmission electron microscopy and geometric phase analysis. The entire strain field of the twin boundary dislocations was mapped and then compared with those of the Peierls–Nabarro and elastic theory dislocation models. The comparison results demonstrated that the Peierls–Nabarro dislocation model best describes the strain field of the twin boundary dislocations in nanocrystalline aluminum.
