Abstract
A microstructurally toughened ceramic-particle-reinforced metal-matrix composite article is disclosed. The article exhibits a complex microstructure. The article exhibits high tensile strength, high elastic modulus and high impact resistance. A process for making the article is also disclosed. The process includes positioning structural elements within a metallic container to define one or more void spaces within the container, introducing a quantity of metallic particles or of a particular mixture of metallic particles and ceramic particles into the void spaces, and consolidating the container, structural elements and particles to form the microstructurally toughened composite article.
