MATERIALS SCIENCE AND ENGINEERING SEMINAR Characterization of Surface Microstructure in Pure Copper After Severe Plastic Deformation by Sliding by Sergey Suslov Ph.D. Final Examination Co-Advisors: Prof. K. Trumble and Prof. S. Chandrasekar ABSTRACT This study concentrates on the characterization of the surface and sub-surface microstructure and texture evolution in pure copper after severe plastic deformation (SPD) in the form of "wave" sliding. This deformation process, based on conventional machining with modifications in the deformation geometry, is used to address the effects of strain and strain rate on the microstructural parameters like the spacing of geometrically necessary boundaries (GNBs) and incidental dislocation boundaries (IDB), fraction of high-angle boundaries and the development of deformation texture. Transmission Electron Microscopy (TEM), Electron Backscatter Diffraction (EBSD) and Vickers microhardness testing were utilized in this work. It was observed that "wave" sliding using -70* and -80* rake angle resulted in the formation of a sub-surface homogeneous strain distribution layer. It was revealed that the material strain-hardened to a larger depth with one pass at a more positive rake angle, and with each consecutive pass (1-8) at -70* rake angle. It was also shown that simple shear was the main deformation mode in "wave" sliding, and the deformation textures were similar to those found in torsion and equal channel angular pressing (ECAP).

SEMINAR REMINDER: S. Visco, PolyPlus Battery Co., Winchell Dist. Lecture, Tue. 11/27/12, 9:00 am, FRNY G140

26 Nov '12

PLEASE NOTE LOCATION IN FRNY, AND 8:30 AM RECEPTION PRIOR TO LECTURE Purdue University School of Chemical Engineering GRADUATE SEMINAR SERIES Peter G. Winchell Distinguished Lecture Series Co-sponsored with School of Materials Engineering Dr. Steven J. Visco, CEO PolyPlus Battery Company, Berkeley, California "The Road to Next Generation Battery Technology: Challenges and Opportunities" November 27, 2012 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: Over the past several decades the United States has lagged significantly behind Japan, Korea, and China in the development and commercialization of advanced electrochemical energy storage technologies. As the world moves towards electrification of transportation and increased use of renewables for grid power, the demand for advanced secondary batteries has already fueled a global race for manufacturing of these key technologies. In order to maintain a competitive position, the U.S. will need to innovate, both in the development of step-change energy storage technologies and in cost-competitive manufacturing of those products. Given the limited introduction of hybrid and fully electric automobiles (xEVs) in the U.S. and abroad, it is clear that widespread adoption of xEVs will not take place until higher performance and lower cost battery technologies are available at scale. Panasonic in Japan recently announced its introduction of a higher performance Li-ion battery incorporating lithium-silicon anode technology, and it is clear that other manufacturers are pursuing similar strategies leading ultimately to lithium metal technology. PolyPlus invented and patented a new generation of water-stable protected lithium metal electrodes, and has advanced the technology under a U.S. DOE ARPA-e program with Corning Incorporated and a recently announced DOE Innovative Manufacturing program with Corning and Johnson Controls. These anodes are enabling for lithium-air, lithium-water, and lithium-sulfur batteries, as well as secondary batteries employing metal oxide cathodes. Accordingly, this presentation will cover some of the relevant challenges and opportunities for scientists looking to make an impact in this exciting field. Bio: Steven Visco is the Chief Executive Officer, CTO, and co-founder of PolyPlus Battery Company in Berkeley, California, as well as a Guest Scientist in the Materials Science Division at the Lawrence Berkeley National Laboratory. Dr. Visco received his Ph.D. in Physical Chemistry from Brown University in 1982 and spent two years as a Postdoctoral Scientist at the University of California at Santa Barbara working on advanced batteries. Dr. Visco then joined the staff at the Lawrence Berkeley National Laboratory as a Principal Investigator in the Materials Sciences Division in 1984 where his research interests have included solid-state ionic devices such as batteries and fuel cells. Steven Visco co-founded PolyPlus Battery Company in 1991. Dr. Visco also serves on the Technical Advisory Boards for the Conrad Foundation and the CIC Energigune Institute in Miñano, Spain. Dr. Visco has published over 75 articles in scholarly journals and books, and currently holds 94 issued U.S. patents and more than 200 international patents. In 2011 Dr. Visco was awarded the International Battery Association Technology Award for "Outstanding Contributions to the Development of Lithium-Air and Lithium-Water Batteries." PolyPlus was recently selected by TIME magazine for its 50 Best Inventions of 2011, and received an Edison Gold Award in April 2012.

PLEASE NOTE LOCATION IN BIRCK MATERIALS SCIENCE AND ENGINEERING SEMINAR InGaAs/InAlAs Heterostructures and Superlattices: An All-Semiconductor Mid-infrared Optical Metamaterial by Bivas Saha Ph.D. Prelim Exam Part I Advisor: Prof. T. Sands ABSTRACT The studies of optical phenomena in nanoscale materials have generated tremendous enthusiasm among researchers in recent years. Metamaterials that have artificial structural elements designed to achieve unusual electromagnetic properties are currently being investigated widely to achieve negative refraction, sub wavelength imaging, density of states engineering and other exotic optical phenomenon. In this talk, I will present an all semiconductor metamaterial based on InGaAs/InAlAs multilayers and superlattices that show negative refraction in the Mid-IR range. The theory behind negative refraction in layered metamaterials is reviewed briefly before discussing the optical characterization and more specifically the negative refraction. Further research into new material systems that might show similar effect and other interesting optical properties are also proposed. Date: Monday, November 26, 2012 Time: 4:00 P.M.
