WORKSHOP OVERVIEW

Testing under laboratory conditions, in air, at standard temperature and pressure has become routine with current instrumentation. However, many materials have intended uses at conditions far from ideal laboratory conditions.

This tutorial focuses on the practical, hands-on requirements for testing in "extreme" environments. International experts in nano- and micro-mechanical testing at high temperature, cryogenic temperatures, in-situ irradiation, and corrosive liquid environments will discuss their experimental approaches for best practices and obtaining reliable data that can be used for engineering purposes.

The presentation will be followed by a live demonstration of mechanical testing at high temperature, whose goal is to obtain material properties as a function of time, stress, and temperature. Samples will include polymer composites and high-temperature intermetallic coatings. Frequency-based techniques that minimize thermal drift will be incorporated. Participants are encouraged to interact with organizers to arrange samples for high-temperature testing during the TMS workshop.

INSTRUCTORS

Dr. Afrooz Barnoush is a professor of Nano- and micro-scale characterization of Materials at the Norwegian university of science and technology (NTNU) in Trondheim. He received the B.A. degree in extractive metallurgy of nonferrous alloys in 1997, and the M.Sc. degree in corrosion engineering in 1999, from Sharif University of technology in Tehran. After four years working in industry as a consultant engineer in the field of corrosion and corrosion protection he moved to Germany where he received his Ph.D. from Saarland University in Germany. The topic of his PhD thesis was "Hydrogen embrittlement revisited by in situ electrochemical nanoindentation". After 4 years research in Saarland University as a tenure track (Habiltant) he moved to NTNU, Trondheim. His current research is centered on development of novel nano and micro scale examination methods to study the environmental effects on mechanical properties.

Dr. Khalid Hattar is a Senior Member of the Technical Staff of Sandia National Laboratories. He received a B.S. in Chemical Engineering from University of California, Santa Barbara in 2003, and a Ph.D. in Materials Science and Engineering from University of Illinois, Urbana-Champaign in 2009. He joined the Radiation-Solids Interaction group at Sandia in December 2008. He specializes in determining the property-microstructure relationship for a variety of structural, electrical, and optical materials through in-situ TEM in various extreme environments.

Prof. David Bahr received his BS and MS in Materials Science and Engineering from Purdue University in 1992 and 1993, and a PhD in Materials Science from the University of Minnesota in 1997. He worked for a short time at Sandia National Laboratories during his PhD before starting as a faculty member in the School of Mechanical and Materials Engineering at Washington State University in 1997. Prior to joining Purdue in August 2012 as Head of the School of Materials Engineering, Dr. Bahr was most recently the Director of the School of Mechanical and Materials Engineering at WSU, and before that served as WSU’s campus-wide Director of Undergraduate Research. He has supervised 2 Post-docs, 18 PhD students, 29 MS students, and over 50 undergraduate researchers in the general area of small scale mechanical behavior. His research spans a range of materials reliability issues, from hydrogen embrittlement to high strain MEMS to dislocation nucleation in metals. In addition to work in metallic systems, he has investigated deformation mechanisms and mechanical properties in piezoelectric thin films, polysilicon, molecular organic crystals, and natural and cellulosic composites.

In 2000 he won the Presidential Early Career Award for Scientists and Engineers for his work with Sandia on DOE stockpile stewardship, in 2003 he received the Bradley Stoughton Award from ASM International, and in 2007 received the Robert Lansing Hardy award from TMS (where he currently serves as a member of the Board of Directors for Membership and Student Development). In 2012 he was named a Fellow of ASM International.

Dr. Karolina Rzepiejewska-Malyska is a Product Manager at Hysitron, Inc. in Minneapolis, MN, USA. In 2005 she received her MSc. Eng. degree in Micromechanics from the Warsaw University of Technology in Warsaw, Poland. In 2009 she received a PhD in Micro-/ Nano- mechanics through a joint collaboration between the Warsaw University of Technology, and the Swiss Federal Materials Laboratory (EMPA) in Thun, Switzerland. Since that time Dr. Rzepiejewska-Malyska has been working in Industry and specializing in small scale mechanics at elevated temperatures. In 2012 she received her MBA in Business Strategy from the University of Strathclyde in Glasgow, United Kingdom and now focuses on the commercial aspect of product development.

WHO SHOULD ATTEND

This workshop is geared for researchers and students who are currently working on, or plan to work on, harsh environment nano- and micromechanical testing. There will be a focus on the "how to" for harsh environment testing, including optimizing testing parameters, avoidance of pitfalls, and managing experimentation for meaningful results in harsh environments.
