Abstract Scope Nanotwinned metals with low-to-intermediate stacking fault energy have been extensively studied as they typically exhibit high strength and ductility. Here we will summarize several cases that focus on highly twinned Al with abundant incoherent twin boundaries. The mechanisms that can introduce growth twins are briefly discussed. The deformation mechanisms of nanotwinned Al are investigated by ex situ and in situ nanoindentation (in transmission electron microscope) technique. These studies suggest that Al with high density growth twins has high strength and significant work hardening capability. This research is funded by DOE-OBES.
