摘要：A method (1200) of forming a component (80) having an internal passage (82)defined therein includes forming (1202) a precursor core (524) having a shape
corresponding to a shape of the internal passage (82), and forming (1204) a hollowstructure (320) around the precursor core (524). The method also includes removing(1206) the precursor core (524) from within the hollow structure (320), and disposing(1208) an inner core (324) within the hollow structure (320) to form a jacketed core (310).The method further includes positioning (1210) the jacketed core (310) with respect to amold (300), and introducing (1212) a component material (78) in a molten state into acavity (304) of the mold (300), such that the component material (78) in the molten stateat least partially absorbs the hollow structure (320) from a portion (315) of the jacketedcore (310) within the cavity (304). Additionally, the method includes cooling (1214) thecomponent material (78) in the cavity (304) to form the component (80). The inner core(324) defines the internal passage (82) within the component (80).
