The Small Business Innovation Research (SBIR) Phase I project will utlize ultrasonic vibrations during pouring of molten metal around a reinforcement insert placed in a mold and during solidification of the composite casting. The proposed processing route will help develop a defect-free metallurgical bond between two dissimilar metals. The proposed technology can be applied to reinforcing lightweight castings including aluminum and magnesium; thereby replacing iron and steel components for automotive, aviation, and defense applications. The use of this technology, therefore, has the potential to contribute to significant energy savings, cost savings, and emission control.

小企业创新研究（SBIR）第一阶段项目将在将熔融金属浇注到置于模具中的增强插入件周围以及复合铸件凝固期间发出超声波振动。 所提出的工艺路线将有助于在两种不同金属之间形成无缺陷的冶金结合。 所提出的技术可用于增强包括铝和镁在内的轻质铸件，从而取代汽车、航空和国防应用中的钢铁部件。因此，该技术的使用有可能有助于显著的能源节约、成本节约和排放控制。
