摘要
The present invention describes a method of casting a metal alloy comprising forming a sand based mold having the geometry to generate a desired object to be cast, placing the mold in an open pressure vessel, filling the mold with a molten metal alloy, immediately thereafter closing and pressure sealing the pressure vessel, pressurizing the sealed pressure vessel with an inert gas for a measured time said predetermined measured time sufficient for the molten metal to cool and fully solidify, depressurizing the sealed pressure vessel and removing the metal filled sand mold, and extracting the desired object from the mold.
