A process for filling openings, including blind holes, through-holes, and cavities, in high temperature components. The process entails forming a powder mixture by mixing particles of at least a base alloy and a second alloy that contains a sufficient amount of a melting point depressant to have a lower melting temperature than the base alloy. The powder mixture is combined with a binder and compacted to form a compacted preform, which is then heated to remove the binder and form a rigid sintered preform. The sintered preform is produced, or optionally is further shaped, to have a cross-sectional shape and dimensions to achieve a clearance of up to 200 micrometers with the opening, after which the preform is placed in the opening and diffusion bonded within the opening to form a brazement comprising the particles of the base alloy dispersed in a matrix formed by the second alloy.

A method and device for retaining position of a consumable core during composite article manufacturing is taught herein by inserting a consumable core having a consumable core body and a plurality of retention artifacts into a composite precursor hollow feature of a composite precursor structure. Then positioning the consumable core such that the plurality of retention artifacts projecting from the consumable core exterior surface at least partially engage with a substantially spatially replicate surface geometry in the composite precursor hollow feature. The consumable core is then consumed as a soluble infiltrant to form a composite article.

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 at least a first material and a second material, and an inner core disposed within the hollow structure. The method also includes introducing a component material in a molten state into a cavity of the mold, and cooling the component material in the cavity to form the component. The inner core defines the internal passage within the component.
