T. G. Nieh


Dr. T. G. Nieh was a professor in Department of Materials Science and Engineering at The University of Tennessee. From 1980 to 1992, he worked at Lockheed Missiles and Space Co. (now Lockheed-Martin Corporation) as a Senior Fellow of Research Laboratory. He subsequently worked at Lawrence Livermore National Laboratory as a Senior Research Fellow until he joined UT in 2004.

Nieh is a world leader in superplasticity and superplastic forming.  He is also widely recognized for his work in several material science disciplines, including multicomponent complex alloys (including high entropy alloys and bulk metallic glasses), nanocrystalline materials, lightweight alloys, metal-matrix composites, intermetallics, refractory metals and nanolaminates.  He published over 400 papers and a textbook on “Superplasticity of metals and ceramics’. He is now serving as Editor-in-Chief, Journal of Intermetallics., has served as Editor, Materials Letters, 2008-2013.

Nieh received the Ph.D. degree in Materials Science and Engineering from Stanford University, the M.S. degree in Physics from University of Washington, Seattle, and the B.S. degree in Physics from National Cheng-Kung University in Taiwan.
