The Small Business Technology Transfer Research (STTR) Phase I project will develop a reliable and effective processing technique to produce a next-generation metal matrix composite comprised of aluminum oxide or silicon carbide nanoparticles dispersed in an aluminum alloy metal matrix. The proposed technology combines the merits of the traditional stirring method and the latest high-intensity ultrasonic processing technology. The use of an impeller stirrer creates a vortex to efficiently pull the lighter nanoparticles into the melt. The use of high-intensity ultrasonic vibration breaks up the nanoparticles clusters and disperses the nanoparticles into the melt. The successful completion of the Phase I project will lead to a breakthrough technology for the processing of metal matrix nanocomposite materials and for the utilization of lightweight materials for applications at elevated temperatures and critical conditions. The technology can be used to reinforce aluminum, magnesium, or other lightweight materials for replacing iron, steel, or titanium components for automotive, power transmission, aviation, and defense applications, leading to significant energy savings, cost savings, and environmental benefits. The U.S. transportation industry continues to focus on the increased use of lightweight alloys for weight and energy savings.

小型企业技术转移研究（STTR）I期项目将开发一种可靠有效的加工技术，以生产由氧化铝或碳化硅纳米颗粒组成的下一代金属基质复合材料，分散在铝合金金属基质中。提出的技术结合了传统搅拌方法的优点和最新的高强度超声处理技术。叶轮搅拌器的使用会产生涡流，以有效地将较轻的纳米颗粒拉入熔体中。高强度超声振动的使用破坏了纳米颗粒簇，并将纳米颗粒分散到熔体中。 I阶段项目的成功完成将导致一项突破性的技术，用于处理金属基质纳米复合材料，并利用轻质材料在升高的温度和临界条件下应用。 该技术可用于增强铝，镁或其他轻巧的材料，以取代铁，钢或钛零件，以用于汽车，电力传输，航空和防御应用，从而导致大量节能，节省成本，节省成本和环境利益。 美国运输行业继续专注于增加轻质合金的体重和节能。
