  • The Science, Technology, and Implementation of TiAl Alloys in Commercial Aircraft Engines
    MRS Proceedings, 2013
    Co-Authors: Bernard Patrick Bewlay, M. J. Weimer, Akito Suzuki, T. Kelly, P.r. Subramanian
    Abstract:

    The present article will describe the science and technology of titanium aluminide (TiAl) alloys and the engineering development of TiAl for Commercial Aircraft engine applications. The GEnx™ engine is the first Commercial Aircraft engine that is flying titanium aluminide (alloy 4822) blades and it represents a major advance in propulsion efficiency, realizing a 20% reduction in fuel consumption, a 50% reduction in noise, and an 80% reduction in NOx emissions compared with prior engines in its class. The GEnx™ uses the latest materials and design processes to reduce weight, improve performance, and reduce maintenance costs. GE's TiAl low-pressure turbine blade production status will be discussed along with the history of implementation. In 2006, GE began to explore near net shape casting as an alternative to the initial overstock conventional gravity casting plus machining approach. To date, more than 40,000 TiAl low-pressure turbine blades have been manufactured for the GEnx™ 1B (Boeing 787) and the GEnx™ 2B (Boeing 747-8) applications. The implementation of TiAl in other GE and non-GE engines will also be discussed. © 2013 Materials Research Society.

  • TiAl alloys in Commercial Aircraft engines
    Materials at High Temperatures, 2016
    Co-Authors: Bernard Patrick Bewlay, Akito Suzuki, Somnath Nag, M. J. Weimer
    Abstract:

    The present article will describe aspects of the science and technology of titanium aluminide (TiAl) alloy system and summarise the low and high temperature mechanical and environmental properties exhibited by different alloy generations. In terms of processing developments, conventional gravity casting and near net shape casting would be discussed in detail. Also newer and non-conventional forging and additive manufacturing routes would be briefly highlighted. Extensive investigations of TiAl alloys have enabled their Commercial implementation in aerospace and automotive industries. The GEnx? engine is the first Commercial Aircraft engine that used TiAl (alloy 48?2?2) for their low pressure turbine blades. Among non GE engines, recently, new ?-stabilised TiAl alloy (TNM) is being used to manufacture LPT blades for PW1100G? engines. TiAl materials and design processes can reduce engine weight and improve engine performance.
