Abstract
Titanium aluminide intermetallics are of engineering interest due to an attractive combination of mechanical properties and density. The paper discusses the properties and processing of titanium aluminides, concentrating on near gamma TiAl compositions. Inherent structural and deformation characteristics are described. The relationship between microstructure and processing is examined with emphasis placed on powder metallurgical HIP'ing and hot deformation processes. Mechanical properties attainable with near gamma TiAl alloys are presented and the effect of ternary elements examined.
