A gamma titanium aiuminide alloy sheet produced by a powder metal process has reportedly been developed for propulsion systems, control surfaces, and general structures of advanced aircraft and spacecraft by NASA Glenn Research Center, Cleveland, Ohio. The alloy and the manufacturing processes together are expected to satisfy the need for relatively economical manufacture of lightweight, high-temperature composites.

The specific strength of the alloy is similar to that of superalloys, while its specific stiffness is greater, and its density is lower. For applications in the ...
