Abstract Scope |
Nanostructured metals with dispersed nanoparticles have been successfully manufactured to offer extraordinary properties for practical applications. This talk is to discuss some recent progress in the processing and properties of nanostructured metals containing nanoparticles. First, it will present a new discovery that nanoparticles can refine metal grains to ultrafine/nano scale by instilling a continuous nucleation and growth control mechanism during slow cooling. The bulk ultrafine grained/nanocrystalline metals with nanoparticles offer an unprecedented thermal stability. Second, it will then discuss about the Selective Laser Melting of aluminum with dense nanoparticles to deliver one of the highest specific Young’s modulus and specific yield strengths among structural metals, as well as an improved specific strength and thermal stability up to 400 °C. Finally, it will focus on a new dispersion mechanism of oxide nanoparticles in molten metals for manufacturing ODS alloys via liquid metallurgy for applications in extreme environments. |
