Grain growth and stabilisation of nanostructured aluminium at high temperatures
Nanostructured (NS) materials have a large stored energy due to their large grain boundary
area and thus tend to be unstable with respect to grain growth during high temperature …

Formation mechanisms of high-density growth twins in aluminum with high stacking-fault energy
Nanotwins readily form in numerous face-centered-cubic (fcc) metals with low stacking-fault
energy (SFE). However, growth twins rarely form in Al due to its high SFE,∼ 120–165 …
