Dr. T.G. Nieh,
Professor, Ph.D., Materials Science and Engineering,
Brief Bio
Dr. T.G. Nieh is currently a professor in Department of Materials Science and Engineering at The University of Tennessee, holding a joint faculty appointment with Oak Ridge National Laboratory. He joined UT in 2004. From 1994 to 2004, Nieh worked at Lawrence Livermore National Laboratory as a Senior Research Fellow. From 1980 to 1992, he worked at Lockheed Missiles and Space Co. (now Lockheed-Martin Corporation) as a Senior Fellow of Research Laboratory.
Nieh is a world leader in superplasticity and superplastic forming. He is also widely recognized for his work in many materials disciplines, including bulk metallic glasses, nanocrystalline materials, lightweight aluminum and magnesium alloys, metal-matrix composites, intermetallics, refractory metals, bioceramics, and nanolaminates. He published over 340 papers and a textbook on “Superplasticity of metals and ceramics’ and is one of the ISI highly-cited materials scientists. He is now serving as an Associated Editor of three international journals: Journal Intermetallics, Journal of Materials Characterization, and International Materials Review.
Nieh received the Ph.D. degree in Materials Science and Engineering in 1980 from
Research Areas
1. Mechanical behavior of bulk metallic glasses
2. Mechanics of cells
3. Synthesis and characterization of nanocrystalline alloys.
4. Synthesis and deformation behavior of nanolaminates.
