ABSTRACT:
A mold vessel having a mold cavity is heated and evacuated. A charge of molten infiltrant is provided into the mold vessel from a source not in vacuum communication with the mold vessel while a reduced pressure is maintained in the mold cavity. Pressure is applied to the molten infiltrant to move it into the mold cavity. The molten infiltrant in the mold cavity is cooled to solidify the molten infiltrant. The mold cavity may contain a preform to produce a metal matrix composite.
