Abstract

The cast and wrought nickel base superalloy M647 has been developed with high mechanical performance and deformability. This study describes an overview of the microstructure and the properties of M647. A full scale forging process has been developed with uniform fine grain distribution. The detrimental effect of thermal exposure at 700 °C ~ 800 °C on mechanical properties was evaluated. M647 showed good mechanical properties and equivalent thermal stability to conventional turbine disk alloys. M647 offers good balance of deformability and mechanical properties with lower cost than powder metallurgy alloys.
