Abstract Scope The present paper will describe the principles, processing, and properties of TiAl Alloys. Significant fundamental research and development of titanium aluminide alloys has led to their application in aircraft and automotive engines. TiAl alloys offer low density in combination with good strength and creep performance up to ~800C. TiAl have several disadvantages, the most notable of which, is the limited ductility at low temperature. Property requirements have led to the evolution range of alloys, that have become categorized as second and third generation alloys. TiAl alloys can be processed by ingot or powder metallurgy, precision casting methods. Each process leads to characteristic microstructures which can be optimized by thermo-mechanical processing and heat-treatments to provide a balance of mechanical properties, such as minimum ductility at room temperature, and sufficient creep strength at elevated temperature. The present presentation will also describe the development of TiAl for aircraft engines (low pressure turbine blades).
