Recent developments of TiAl alloys towards improved high-temperature capability

International Symposium on Niobium for High Temperature Applications

Titanium aluminide alloys based on relatively large Nb additions, together with fine dispersions of precipitates, exhibit attractive thermo-physical properties, which extend the service range of conventional TiAl alloys. Engineering alloys can be tailored for strength, toughness, creep resistance, and environmental stability. These concerns are addressed in the present paper through a global commentary on the physical metallurgy and the associated processing technologies. (AU)
