Economic stakes and fields of application
TiAl based intermetallic alloys

Reducing greenhouse gas emissions is more than ever a priority for the transport industry, and is in line with the European Commission's ACARE recommendations. . One of the main levers for achieving these objectives is the development of new engine architectures with higher efficiency and advanced structural materials enabling mass reductions. TiAl-based alloys have been developed for over twenty-five years, and are now reaching a degree of maturity that positions them with a high TRL (Technological Readiness Level) for various high-temperature applications.

The choice of applications is also dictated by the level of mechanical properties required and the maximum operating temperature. TiAl's...
