STTR Phase I: Reinforcement of Lightweight Material Castings with Dissimilar Metals

小型企业创新研究（SBIR）第一阶段项目将利用超声波振动在浇铸过程中熔化的金属周围的强化插入放置在模具和复合铸件的凝固过程中。提出的加工路线将有助于在两种不同金属之间建立无缺陷的冶金结合。该技术可应用于铝、镁等轻铸件的补强；从而取代钢铁部件的汽车，航空和国防应用。因此，这项技术的使用有可能为显著的能源节约、成本节约和排放控制做出贡献。

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.
