Shear-Induced Mixing Governs Codeformation of Crystalline-Amorphous NanolaminatesDeformation of ductile crystalline-amorphous nanolaminates is not well understood due to the interplay of interface mechanics, shear banding, and deformation-driven chemical mixing. Here we present indentation experiments on 10 nm nanocrystalline Cu–100 nm amorphous CuZr model multilayers to study these mechanisms down to the atomic scale. By using correlative atom probe tomography and TEM we find that crystallographic slip bands in the Cu layers coincide with noncrystallographic shear bands in the amorphous CuZr layers.
