中文摘要	Dislocation plasticity of Au/Cu multilayer with 100 nm scale was investigated by three-point bending tests. The authors found directly that clear slip lines appeared inside the grains ranging from 60 to 190 nm. The finding implies that the potential dislocation plasticity is still the dominant deformation mechanism in the material. Statistical evaluation of the mean spacing between slip lines reveals the effect of the length scale on homogeneity of plastic deformation. The critical length scale for dislocation-dominated deformation of the nanoscale material is found to be similar to 15 nm.
