Abstract
Methods for producing components for use in high temperature systems that include reacting a fluid reactant and a porous preform that has a pore volume and contains a solid oxide reactant that defines a solid volume of the porous preform. The method includes infiltrating the fluid reactant into the porous preform to react with the solid oxide reactant to produce a oxide/metal composite component, during which a displacing metal replaces a displaceable species of the solid oxide reactant to produce at least one solid oxide reaction product that has a reaction product volume that at least partially fills the pore volume. The oxide/metal composite component includes at least one oxide phase and at least one metal phase. The component is exposed to temperatures greater than 500° C. and the at least one oxide phase and the at least one metal phase exhibit thermal expansion values within 50% of one another.
