Fig. 5: MD simulations of local atomic packing and shear response of the base alloy and alloy with O doped.
From: Substantially enhanced plasticity of bulk metallic glasses by densifying local atomic packing
A slice (6.25 × 6.25x × 0.35 nm3) taken from a cubic box with 13,500 atoms is shown as a representative example of atomic packing in O-doped MGs. a shows that local regions around doped O atoms are more densely packed. Atomic number density (b) and potential energy (c) mapping of the O-doped alloy. The distribution histogram of local shear strain for the base (d) and O-doped alloy (e) at strains of 4% and 8%. Insets in d and e are the atomic shear strain map at a strain of 4% and 8%.
