Abstract

A microstructurally toughened metallic article is disclosed. The article includes discrete metal regions which are enclosed within and separated from each other by a network of metal. The regions are bonded to the network to form stable interfacial boundaries. The article exhibits high impact resistance. The process for making the article is also disclosed. The process includes positioning a plurality of structural elements within a container to define one or more void spaces within the container, introducing a quantity of metallic particles into the void spaces, and then consolidating the container, structural elements, and particles to form the microstructurally toughened article.
