TOOLS FOR COMBINATORIAL MACROMOLECULAR CRYSTALLIZATION

Not Available Triton Systems Inc. proposes to use a high strain-rate superplastic forming (HSR-SPF) technology to fabricate complex shaped Nanoparticulate discontinuously reinforced aluminum (DRA) components. Nanoparticulate DRA offers the strength and stiffness advantages of conventional DRA, which is reinforced with micron scale particles, but has the added advantages of HSR-SPF formability without cavitation and ease of machining using conventional tooling. The proposed innovative manufacturing technology for producing Nanoparticulate DRA components using high strain-rate superplastic forming will, for the first time, will make SPF components, both Nanoparticulate DRA and unreinforced aluminum, cost competitive. It will enable entry of SPF technology into a number of new industries such as the automotive sector. The proposed Phase I program will develop the process technology and refine the materials required to achieve the necessary form, fit and function of the component. A first generation version of the selected component will be fabricated for bench testing. In Phase 11, a full-scale component will be fabricated and tested. BENEFITS: The proposed technology will enable the cost effective entry of high specific strength and stiffness metal matrix composites into large commercial markets. In addition to DoD system components, potential applications include parts for the automotive industry, commercial gas turbine engines, and high-end recreational sporting goods.
