|On-Site Speaker (Planned)
Titanium aluminide has been for years identified as a solution for weight reduction in the LPT (Low Pressure Turbine) of a turbo-engine. The improved specific mechanical properties of these intermetallic alloys, when compared to Ni-based superalloys, have pushed Safran and other major aero-turbine producers to introduce them in their latest and newest generations of turbines. Today, TiAl LPT blades are a reality as they enter in mass production phase. Different alloy compositions as well as production routes have been developed and adapted to various applications and specific requirements. This application-oriented development leads to different alloy families, but we will focus in the talk on the ones able to handle higher stresses and temperatures. In addition to mechanical properties, oxidation resistance and ageing in air environment are major challenges to overcome.
