Abstract The metallic nanomaterials are expected to have unique mechanical properties, such as high strength,more ductility and perfect elastoplasticity.The mechanical properties of metallic nanomaterials are summarized in this paper, including high strength, ductility, strain hardening and super-plasticity. And some factors are also discussed briefly, which are likely to affect the mechanical properties.
Key words nanomaterials, ductility, super-plasticity
