Abstract : In a method for casting metal alloys, a molten metal alloy is introduced into a mold of a desired configuration containing a core material fabricated to a desired shape from titanium nitride while maintaining the mold under a vacuum. After allowing the mold to cool slowly to room temperature, the casted metal alloy with the core material exposed at one end is removed from the mold and immersed in a boiling caustic solution, thereby causing the titanium nitride core material to decompose. The casting so obtained has a smooth inner surface, an indication that no chemical reactions have occurred between the alloy and the core material. (Author)
