Abstract

The casting of metal matrix composites (MMC's) is associated with numerous precautions necessary to prevent the formation of inclusions and imperfections in the molten metal during solidification. The disclosure relates to a method of casing metal matrix composites in which molten metal or alloy is poured under gravity into an enclosed mould (2), the method including the steps of allowing the molten metal or alloy to solidify in the said cavity, thereby to form the required casting; and removing the casting from the mould, characterised in that there is used a bottom fill mould wherein the molten metal or alloy is fed to the mould substantially exclusively via a sprue (3) inclined at an angle of between 45{ and 75{ to the horizontal, the sprue opening substantially directly into the mould cavity (2) at its lowermost point. An advantage of the method is that casting of metal matrix composites can be achieved more reliably.
