Cast superalloys are important materials that are directly used in the production of key components such as guide vanes and turbine blades for aero engines. It is related to the life and safety of aero engines, therefore, the quality of controlled casting superalloy parts has always been highly valued by domestic and foreign production units and metallurgists.
