The proposed research addresses the need for materials capable of withstanding everincreasing temperatures and harsher chemical environments. Such materials will enable greater efficiencies and performance, reducing carbon emissions and providing a competitive advantage to the industry and defense of the United States of America. This SBIR effort will extend Modumetal by Design (MbD), a unique alloy manufacturing process, to the scalable and low-cost net-shape production of functionally graded and laminated niobium-silicide composites exhibiting spatially tailored structure and chemistry. The proposed composites improve thermo-mechanical properties over conventional nickel-based superalloys, and will incorporate in-situ strength, creep resistance, and oxidation protection through functional gradation and nano- and micro-scale lamination. The proposed work leverages our existing experience and infrastructure related to the production of nanolaminated and functionally graded alloys. Commercial Applications and Other
Benefits: The proposed technology would have direct commercial applications ranging from Oil and Gas to Aerospace, with potential secondary applications in superconductors
