Abstract

Metal matrix composites are manufactured in a vacuum die casting machine. Solid aggregate material, at least 65 volume percent, is placed in a die, the die is evacuated and heated, and molten metal is driven by a piston to infiltrate the solid aggregate material where it subsequently solidifies to form a metal matrix composite.
