Notes:
A new kind of cast & wrought (C&W) Ni-Co base superalloys named as “TMW alloys”was developed recently for compressor and turbine disk of gas turbine engines in the HighTemperature Materials 21 Project at the National Institute for Materials Science (NIMS) in Japan.These Ni-Co base superalloys combine the characters of two kinds of γ- γ’ two-phase alloys (Ni-baseand Co-base superalloys) and can be fabricated by cheap cast and wrought processing route. Theresults showed that some of these TMW alloys have superior tensile strength at temperatures up to750 °C and higher creep resistances up to 725 °C than commercial UDIMET 720 LI alloy
