Advanced industrial gas turbines are becoming preferred devices for worldwide power generations and large ship power in recent decades due to its outstanding advantages of high thermal efficiency and low pollution. Casting superalloy is the key material for industrial gas turbine blades in hot section components, and to a certain extent their performance and preparation level determine the levels of power, efficiency and service life of the industrial gas turbines. This paper outlines the current research and application status and shows the development trends of manufacturing technology of casting superalloy for industrial gas turbines and turbine blades. In the future, technologies such as advanced directional solidification and "materials genome engineering" will be used in the research and manufacture of casting superalloy for industrial gas turbine blades. Meanwhile, the directional and single crystal superalloy will be used more and more widely in advanced industrial gas turbines.
