摘要	Shear band, a kind of unstable plasticity behavior, limits deformability of nanoscale materials, however the basic mechanism for such plasticity instability is still not understood well. Here, we found that the plastic deformation within the shear band of 25 nm-Cu/Au nanolayered composites is mainly contributed by the dislocation-dominated non-crystallographic rotation of the Cu/Au interface without destroying the crystallographic orientation. Homogeneous dislocation transmission across the transparent interface led to the non-crystallographic rotation to accommodate the geometrical requirement. The crystallographic relationship and structure in the interface zone can keep intact until the interface zone in the heavily-thinned layers becomes into amorphization. (C) 2018 Elsevier B.V.
