Linking stress-driven microstructural evolution in nanocrystalline aluminium with grain boundary doping of oxygen

Nanocrystalline metals are ultra-strong because of the large fraction of material at the grain boundaries, but this also leads to instability under applied loads. Here, the authors deepen our understanding of this by linking stress-driven motion of grain boundaries to grain boundary chemistry.
