[HTML][HTML] A nanodispersion-in-nanograins strategy for ultra-strong, ductile and stable metal nanocomposites
Nanograined metals have the merit of high strength, but usually suffer from low work
hardening capacity and poor thermal stability, causing premature failure and limiting their
practical utilities. Here we report a “nanodispersion-in-nanograins” strategy to
simultaneously strengthen and stabilize nanocrystalline metals such as copper and nickel.
Our strategy relies on a uniform dispersion of extremely fine sized carbon nanoparticles
(2.6±1.2 nm) inside nanograins. The intragranular dispersion of nanoparticles not only …
