    摘要: A metal-nanostructure composite includes a nanostructure-metal matrix composite. The nanostructure-metal matrix composite includes a host metal and nanofiller dispersed in the grains of the metal. The nanofillers can include both one-dimensional nanostructures (e.g., nano-tubes, nano-rods, nano-pillars, etc.) and two-dimensional nanostructures (e.g., graphene, nano-foam, nano-mesh, etc.) to improve the radiation resistance and mechanical properties of the host metal. A method of manufacturing the metal-nanostructure composite includes obtaining carbon nanotubes (CNTs) and encapsulating the CNTs with metal particles. The method also includes consolidating the encapsulated CNTs and forming (e.g., via extrusion) the consolidated metal/CNTs to produce the metal-nanostructure composite.
