A series of iron, nickel, and cobalt base alloys were permanent mold cast under varying conditions to evaluate techniques for improving the integrity of die casting. By appropriate control of heat flow it is possible to achieve permanent mold casting with mechanical properties equivalent to investment castings. Liquid-solid slurries were cast Rheocasting to evaluate casting properties and opportunities for enhanced mold life with a reduced temperature casting process. Casting properties are acceptable. It is not clear that there is enhanced mold life by this process.
