METHOD OF MAKING A COMPOSITE CASTING AND CASTING PRODUCED THEREBY Abstract of the Disclosure A method of making a composite casting wherein a casting mold is provided for receiving a melt and a preformed metallic or intermetallic insert is positioned in the mold cavity. The preformed insert includes a working portion for incorporation in the casting and gas seal-forming means located at a region of the insert at least outboard of the insert portion. A melt is introduced into the mold about the insert and is then solidified to provide a composite casting having the insert working portion disposed in the solidified melt and as-cast gas seal regions located outboard of the insert working portion in the casting. The casting is then subjected to elevated temperature and isostatic gas pressure conditions wherein the as-cast gas seal regions are effective to inhibit gas penetration between the insert working portion and the solidified melt therearound so as to permit formation of a sound, void-free metallurgical bond therebetween. The hot isostatically pressed casting can then be trimmed to remove, if desired, those outboard portions containing the gas seal regions, leaving a finished casting having the insert working portion metallurgically bonded therein in a sound, void-free manner.
