SBIR Phase I: Niobium Silicide Intermetallics Castings for the Next Generation of Very High Temperature Applications

这个小型企业创新研究(SBIR)第一阶段项目将测试一种新的生产技术的可行性，以生产一类先进的难熔金属间化合物的负担得起的近净形状部件。以Nb(Nb)为基础的金属间化合物将允许许多非常高温的应用革命性地提高工作温度。第一阶段将采用一种创新的反应金属熔模铸造方法，为制造复杂形状创造一种经济高效和坚固耐用的工艺。第二阶段将探索生产实际部件的策略。反解放的商业应用是那些在非常高的温度下的应用，例如现在由单晶镍基高温合金制成的涡轮翼型。预计未来飞机系统的燃油效率和推重比将达到前所未有的水平。

0128423ChenThis Small Business Innovation Research (SBIR) Phase I project will test the feasibility of a new production technology for affordable near-net shape components of a class of advanced refractory metal intermetallic composites. Niobium (Nb)-based intermetallics will permit a revolutionary increase in operating temperatures for many very high temperature applications. Phase I will employ an innovative reactive metal investment casting method to create a cost-effective and robust process for manufacturing complex shapes. Phase II would explore strategies for producing actual components.Anticipated commercial applications are those at very high temperatures, such as turbine airfoils now made of single crystal nickel-based superalloys. Unprecedented levels of fuel efficiency and thrust-to-weight ratio are expected for future aircraft systems.
