  • Superalloy rotor component and method of fabrication
    Patent number: 9114488
    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.
    Type: Grant

  • Clad power metallurgy article and method for producing the same
    Patent number: 6773824
    Abstract: A clad article of a substrate of one powdered metal that is clad with a second dissimilar powdered metal. A separation layer may be provided between the substrate and the clad layer to separate these layers during consolidation and to facilitate bonding thereof. The consolidation operation may be performed by hot isostatic pressing of the powders within a deformable container.
