(color online) Representative CNA snapshots of Cu-4.3 at.% Ni bicrystal with Σ9(114) GB under the shear deformation along direction. SF₂ exhibits the intrinsic stacking faults, accompanied with the leading partial dislocation motion. Under loading shear strain ε = 0.099, 0.192, 0.274 structures are changed as shown in panels (a)–(c) correspondingly.
