摘要： In a non-limiting example, an article having a body including a nickel-based superalloy is provided. The nickel-based superalloy has a microstructure that includes a gamma phase matrix and a gamma prime phase including a plurality of rafting-resistant gamma prime particles dispersed in the gamma phase matrix. The plurality of the rafting-resistant gamma prime particles has an average particle perimeter of about 3 microns to about 15 microns, an average aspect ratio of about 1.2 to about 3, and where the microstructure of the nickel-based superalloy is substantially uniform throughout the body.

摘要： Embodiments of the disclosure provide a turbomachine component (100), including: a base portion (116) configured for mounting on a rotor (12); an airfoil portion (102) having a first end coupled to the base portion (116), and a second end opposite the first end. A creep resistance of the airfoil portion (102) is greater than the base portion (116), and a fracture toughness of the airfoil portion (102) is less than the base portion (116). A tip portion (112) may be coupled to the second end of the airfoil portion (102). A creep resistance of the tip portion (112) is less than the airfoil portion (102) and greater than the base portion (116). A fracture toughness of the tip portion (112) is less than the base portion (116) and greater than the airfoil portion (102).

摘要： A method (700) of forming a component (80) having an internal passage (82) defined therein includes positioning (702) a jacketed core (310) with respect to a mold (300). The jacketed core includes a hollow structure (320) formed from a first material (322), an inner core (324) disposed within the hollow structure, and a core channel (360) that extends from at least a first end (311) of the inner core through at least a portion of inner core. The method also includes introducing (704) a component material (78) in a molten state into a cavity (304) of the mold, such that the component material in the molten state at least partially absorbs the first material from the jacketed core within the cavity. The method further includes cooling (706) the component material in the cavity to form the component. The inner core defines the internal passage within the component.
