AbstractThe advanced cast & wrought (C&W) superalloys for turbine disc applications have low temperature bearing capacity and poor processing ability compared with the powder metallurgy (PM) superalloys. Recently, a new kind of C&W Ni-Co base disc superalloys, named as TMW alloy, has been developed on the basis of an innovative concept. Full-scale pancakes (440 mm in diameter and 65 mm in thickness) with an average grain size of about 10 pm were successfully manufactured by a conventional C&W processing route. TMW alloys can provide 58-76 degrees C temperature advantages over alloy U720Li in 0.2% creep strain life under 630 MPa and are comparable with the advanced PM disc superalloys. In this work, the alloy design, preparation processing capacity, micro-structural control, performance characteristics and deformation strengthening mechanisms were briefly introduced.
