Research on Ductile Phase Toughening of Tungsten for Fusion Reactor Materials
Chuck Henager, Pacific Northwest National Laboratory, Richland, WA 99352
Since joining PNNL in 1976, Dr. Henager has worked in a variety of materials science areas, concentrating on radiation effects, mechanical properties and strength of materials, and computational materials science of interfaces and deformation in metals and alloys. He completed a year assignment to the US Department of Energy, Basic Energy Sciences, Materials Science and Engineering where he helped plan a major new initiative in Computational Materials Science in 1998. He has published over 115 papers and articles, has edited two books, and has eight U.S. Patents. He is also Adjunct Professor, Dept. of Materials Sciences, University of Washington, Seattle, WA. Some specific projects that he is involved with include: 1) PI on a 3-year project exploring the development of tough W-based composites for Fusion Reactor Materials in collaboration with UCSB, 2) PI of a project developing SiC-based alloys for advanced nuclear systems for Office of Nuclear Energy, 3) has published extensively in the area of deformation using atomistic models in metals and nanolayered materials. He has also explored radiation damage effects in materials, including nanolayered composites and SiC/SiC composites. The models deal with fundamental radiation effects, thermal conductivity, and phase stability issues, and 4) Pre-ceramic polymers and solid-state displacement reactions are being studied for joining SiC-based ceramics and composites for Office of Fusion Energy Sciences.
