High integrity titanium aluminide compacts
Metal Powder Report, 1991 Abstract Titanium aluminide alloys are important candidates for applications in advanced gas turbine engines and high mach airframes. Compared with conventional titanium alloys, the aluminides are lower in density, higher in modulus, and have better high temperature oxidation and creep resistance.

Titanium Aluminides for Aerospace Applications
Superalloys 1992 (Seventh International Symposium), 1992 The U. S. aircraft industry has realized much of its success because of the steady improvements in specific thrust (thrust/weight) and in specific fuel consumption (fuel used/unit of thrust). The desire to further improve specific thrust both for IHPTET (Integrated High Performance Turbine Engine Technology) and NASP (National Aerospace Plane) programs
