Abstract:

Research has been carried out in three materials systems 1 Advanced Metallics NbTisilicides and gamma TiAl are being developed as high-temperature structural materials. The research included chemistryprocessingmicrostructureproperty relations to provide a balance in mechanical properties and oxidation resistance. Fundamental studies on microstructures and mechanical behavior in these systems have been performed using a variety of analytical and computational tools to predict aspects of plasticity, creep and fracture on length scales connected to electronic, atomistic, and continuum levels. 2 Advanced Metallic Composites Deformation, fracture, and creep studies have been performed on discontinuously reinforced Al and Ti composites. Projects have been initiated on 1 microstructural simulation in these composites, and 2 crystallization kinetics and topology-based models for amorphous Al alloys. 3 Ceramic Composites Research has been conducted on a number of interrelated projects, including interface control, experimental mechanics and models, new composite systems, processing, and structure-property understanding.
