Established the Center for Friction Stir Processing in 2000, and joined a four-university NSF Industry/University Cooperative Research Center in 2004. UMR site is supported by General Motors, Boeing- St. Louis, Pacific Northwest National Laboratory and Friction Stir Link. Established a state-of-the-art friction stir welding facility with three machines (a two-axis machine funded by NSF-IMR program in 2000, a robotic friction stir welding machine funded by ONR-DURIP program in 2004 and a friction stir spot welding machine funded by AFRL under CAMT program). Established microstructure-property correlations in high strength aluminum alloys and composites.
Demonstrated use of friction stir processing for superplasticity. This is a new concept that enables several new technical development.
Surface composite fabrication for local wear resistance enhancement.
Microforming of MEMS components.
Friction stir channeling as a new technique to fabricate integral channel heat exchangers.
Several of these concepts are being developed for the first time and the University of Missouri filed five patent applications. So far three patents have been awarded.
• Elevated temperature deformation mechanism in high strength aluminum alloys
Developing principles for microstructural design of high strength aluminum alloys.
Establishing fundamental deformation mechanisms in nanophase aluminum alloys, Al-Sc-Zr-Mg-SiC composites and amorphous aluminum alloys. The work is primarily focused on elevated temperature mechanical behavior. We have used secondary processing to obtain a combination of 700 MPa strength and >8% ductility in Al-Ni-Y alloys in collaboration with Pratt & Whitney.
The Al-Ni-Y work has resulted in several P&W-UMR joint invention disclosures in 2006.
Started activities on elevated temperature formability of bulk metallic glasses. Zr-based and Mg-based systems are being investigated.
Started activities on materials and process selection for alternative energy systems. Particular focus is on 3-10 kW wind and hydrokinetic energy systems.
University of California, Davis March 1994-July 1999
• Processing and mechanical behavior of ultrafine grained materials
Synthesized and characterized a number of ultrafine grained metallic and composite materials. These materials have quite a unique mechanical behavior.
Successfully consolidated nanocrystalline alumina (<50 nm) in less than 10 minutes, finest fully dense alumina reported in the literature.
Processed nano alumina matrix composites to evaluate the concept of residual stress toughening and ductile phase toughening in ceramics matrix composites.
