Abstract
Bending tests of submicrometer Al pillars were performed in-situ in a transmission electron microscope (TEM). The unique findings are: 1) the Al crystal in the bent region experienced substantial lattice distortion, as well as grain refinement; 2) a disordered dislocation configuration arising from a random distribution of low angle grain boundaries (LAGBs). This observed disordered dislocation configuration is in contrast to the prediction on the basis of the theory of strain gradient plasticity, for bulk materials subjected to plane strain bending.115
