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.

0128423Chen这个小企业创新研究（SBIR）第一阶段项目将测试一种新的生产技术的可行性，该技术用于生产一类先进的难熔金属间化合物复合材料的可负担的近净形部件。 铌（Nb）基金属间化合物将允许许多非常高温应用的工作温度的革命性提高。第一阶段将采用创新的反应金属熔模铸造方法，为制造复杂形状创造一个具有成本效益和鲁棒性的工艺。第二阶段将探索生产实际部件的战略，预期的商业应用是那些在非常高的温度下，如涡轮机翼型现在由单晶镍基高温合金制成。 未来飞机系统的燃油效率和推重比有望达到前所未有的水平。
