Abstract
A rotor component assembly including at least one void space formed therein that provides for reduction in weight of the component and/or cooling of the component during operation. The rotor component is formed by positioning a coated mild steel insert within a mold having an internal cross-section substantially the same in dimensions as the final rotor component. The mold is filled with a superalloy metal powder and undergoes hot-isostatic pressing to consolidate the powder about the coated core insert and form a superalloy structure. The mold is removed from about the superalloy structure and the core insert is removed from within the superalloy structure, thereby defining the at least one internal void within the rotor component.
