- 摘要：
- Nanostructured metals are strong, but have poor ductility and thermal stability, and require extreme preparation conditions. We conceive a strategy of ultrahigh extensibility enabled by van der Waals interface for fabricating bulk nanostructured metals via plastic deformation under moderate conditions. As an example, laminated copper grains are continuously refined to be less than 50 nm in thickness, owing to interlayer sliding of multilayer graphene and co-deformation of CuC along their interfaces in a conventional cold-rolling process.
