Novel Properties of Nanostructured Metals

Due to the ultrafine grains (or domains or particles) and a high density of grain boundaries (or generally interfaces) in nanostructured materials, many properties and performance of the materials are expected to be significantly varied with respect to their coarse-grained counterparts. Extensive investigations over the past decays indicated that the nanostructured metals do possess some novel properties that may find technological applications in industry. In this talk, a brief survey of current status of investigations on properties of nanostructured metals will be summarized with emphasis on the following properties.
