Advancement in Titanium Aluminide and its High Temperature Oxidation Behaviour

The present contribution aims at a brief introduction to titanium aluminides and scope of its applications especially in high temperature oxidation resistance applications. The detailed description would include classifications of titanium aluminides, microstructures developed in this system, properties of materials with different microstructural morphology, the fabrication routes usually followed for the development of this aluminides and oxidation behaviour of this alloy. The oxidation behaviour of titanium aluminides is very much dependent upon its microstructures, composition and phases present. The scope of enhancement of oxidation resistance property of this alloy by changing its microstructure, composition and a sui surface treatment technique will be discussed. Finally, the future scope of research on the titanium aluminide with high temperature oxidation resistance application will be presented.
