This research focuses on developing and applying modeling and simulation methods to explore broad aspects of metal alloy development. Target materials include but are not limited to high-temperature structural materials such as Ni-based superalloys, refractory metal intermetallics, and Ti-Al alloys. Current interest areas include modeling plasticity at the atomic and micron scales using electronic structure, atomistic, and dislocation dynamics methods. Research in this area includes size scale, chemical, ordering, solution, and precipitate effects. In addition, free energy models, based on first principles methods, are used to predict stability and the nature and evolution of defects in these materials. This includes properties of both the liquid and solid phases, and the microstructural evolution of complex metal alloys. Significant computational resources are available through the High-Performance Computing Modernization Office to perform large-scale calculations, analysis, and visualization. Research is closely integrated with the group’s three-dimensional characterization and microscale plasticity experimental techniques, and the AFRL/RX characterization facility.
