Molecular dynamics is employed to study stress-strain curves obtained during high strain rate deformation of nanocrystalline Al-10.2 at.% Co alloy with (i) randomly distributed Co atoms (Al-Co substitutional solid solution) and (ii) Co atoms segregated in grain boundaries (GBs) of the alloy. The eff...
