Abstract: A method of producing composites of micro-engineered, coated particulates embedded in a matrix of metal, ceramic powders, or combinations thereof, capable of being tailored to exhibit application-specific desired thermal, physical and mechanical properties, such as High Altitude Exo-atmospheric Nuclear Standard (HAENS) I, II or III radiation protection, to form substitute materials for nickel, titanium, rhenium, magnesium, aluminum, graphite epoxy, and beryllium. The particulates are solid and/or hollow and may be coated with one or more layers of deposited materials before being combined within a substrate of powder metal, ceramic or some combination thereof which also may be coated. The combined micro-engineered nano design powder is consolidated using novel solid-state processes that prevent melting of the matrix and which involve the application of varying pressures to control the formation of the microstructure and resultant mechanical properties.
