Research Interests and Projects

            Research in our group encompasses the areas of physical metallurgy; solid-solid phase transformations; high-resolution transmission/scanning electron microscopy; mechanical behavior and deformation mechanisms; and microstructure-property relations, with special emphasis on advanced lightweight, high temperature alloys and intermetallics, notably the titanium and niobium aluminides, niobium/molybdenum silicide-based alloys, nickel-base superalloys, advanced aluminum alloys and nanoscale materials. Funding for this research has come from a variety of sources: industry (Rolls Royce, Cummins, GEAE), state institutions (OBR), defense/government laboratories (AFRL, NASA-Lewis) and federal agencies (NSF, AFOSR, DoE). We also have active collaborations with scientists at the Air Force Research Laboratory (AFRL), the Argonne National Laboratory (ANL), the Oak Ridge National Laboratory (ORNL), Lawrence Livermore National Laboratory (LLNL) and the National Institute of Materials Science (NIMS) in Japan. The research projects fall under two broad categories of materials length scales and are described below.
