Abstract Scope Hypersonic environments require materials that have a combination of strength and high melting temperatures. However, these properties usually make materials brittle and fracture prone at low to moderate temperatures where resistance to fracture is needed. In this talk, we introduce metal-ceramic composite that can be fracture resistant at low temperatures but phase transforms to a UHTC at high temperatures. Specifically, we shown how transition metal carbide/transition metal multilayers can be designed to phase transform from a composite to a monolithic ceramic that has UHTC properties and creep resistance. This is accomplished by integrating computational modeling of the phase transformation, theoretical modeling of the fracture resistance, and experimental demonstration of the phase transformation properties. We further demonstrate how these materials can be optimized for the phase transformations and how the can be synthesized from standard processing routes.
