Abstract
A method of forming a component having an internal passage defined therein includes positioning a jacketed core with respect to a mold. The jacketed core includes a hollow structure formed from a first material, and an inner core formed from an inner core material disposed within the hollow structure. The method also includes introducing a component material in a molten state into a cavity of the mold, such that the component material in the molten state at least partially absorbs the first material from a portion of the jacketed core within the cavity. The method further includes cooling the component material in the cavity to form the component, and removing the inner core material from the component to form the internal passage.
