Advances in gas-turbine development are driven by the need to reduce fuel consumption, emissions and costs. From the material aspect, these requirements enhanced the development of highly creep and oxidation resistant materials of greater temperature potential than titanium alloys and of lower density than nickel superalloys. After almost three decades of intensive fundamental research and development activities, titanium aluminides based on the ordered γ -TiAl phase have found applications in automotive and aircraft engine industry. The advantages of this class of innovative high-temperature materials are their low density and their good strength and creep properties as well as their good oxidation and burn resistance. Advanced TiAl alloys are complex multi-phase alloys which can be processed by ingot or powder metallurgy as well as precision casting methods or even forging. Each process leads to specific microstructures which can be altered and optimized by thermo-mechanical processing and/or subsequent heat treatments.
