Actual alloy and process development for high temperature applications in aerospace and automotive sectors is strongly aimed at reaching the demands on reduction of CO2 emissions responsible for the green house effect. Besides weight reduction the main objective resides in improving engine performance and efficiency. Last generation intermetallic titanium aluminides (TiAl) have a big potential to reach this goals. Nevertheless TiAl is a very demanding material which requires very sophisticated processing routes. Access has developed a whole processing route for the production of high quality near-net-shape TiAl cast components in which investment and centrifugal casting merge. Although the feasibility of the technology is proven in a pilot phase, it is necessary to qualify the process for series production. With aid of a new developed automated centrifugal casting facility Access and its partners are conducting a comprehensive qualification process for the production of both aerospace and automotive components.
