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.

0128423 Chenthis小型企业创新研究（SBIR）I阶段项目将测试新生产技术用于负担得起的一类高级耐火金属金属间金属层材料的近网状组件的可行性。 基于NIOBIUM（NB）的金属间学将允许许多非常高温应用的工作温度革命性升高。第一阶段将采用创新的反应性金属投资铸造方法来创建一个成本效益且强大的过程来制造复杂形状。第二阶段将探索生产实际组件的策略。期待的商业应用是在非常高温下的策略，例如现在由单晶镍的超级合金制成的涡轮机翼。 未来飞机系统的燃油效率和推力重量比率为前所未有的水平。
