Our division is engaged in the research and development of titanium-based alloys, intermetallics, and composites. Emphases are placed on the fundamental understanding of processing route/microstructure relationships aided by computer simulations, with a view toward improving properties. Clean melting, contamination-free powder production, investment casting, hot-die forging, and wire and sheet production technologies are being developed. An integrated approach to producing light, endurable parts by combining materials processing and near-net shaping is being explored.
