The Department of Defense (DOD) is seeking proposals for the advancement of scandium use in metal alloys for U.S. weapon system production and sustainment. Scandium has unique properties that can significantly increase the performance of aluminum alloys, allowing for reduced weight designs and increased resistance to high temperature and corrosion. The DOD is interested in exploring future defense industrial base uses for scandium, including its substitution for expensive materials and its compatibility with additive manufacturing techniques. Potential applications for scandium-aluminum alloy include missiles, aircraft, space launch vehicles, satellites, soldier systems, military ground vehicles, marine applications, and other weapon systems. The DOD is particularly interested in engaging small businesses to develop and expand expertise and production capacity in scandium-containing materials. The project duration for Phase I is 12 months with a cost of $100,000, while Phase II has a duration of 24 months with a cost of $1,000,000. Proposals should demonstrate proof of concept and include collaboration with established materials companies and DoD weapon system program offices. The goal is to develop commercially viable sources of scandium supply for transition to production in support of DoD and its supply chains. Phase III proposals will be accepted after the completion of Phase I and II projects, with no specific funding associated.
