... is caused by an increase in dislocation density at shallow depths, which is in agreement with the strain-gradient plasticity theories. In the work described below, we investigate the ISE in polycrystalline high-purity fcc materials. We tested aluminum, a high-stacking fault energy (SFE) material, and α...
