    Abstract: A method for making a composite material. Porous reinforcing material such as fiber material is charged into a container which has an opening; then substantially all of the atmospheric air in the container and in the interstices of the reinforcing material is replaced by substantially pure oxygen; and then molten matrix metal is admitted into the container through the opening so as to infiltrate into the interstices of the reinforcing material. During this infiltration the oxygen within the container and in these interstices is absorbed by an oxidization reaction, and thus substantially all the gas present within the interstices of the reinforcing material is disposed of, thus not hampering the good infiltration of the molten matrix metal into the reinforcing material. Thus a high quality composite material is formed. The oxidization reaction may either be with the molten matrix metal itself, or with a getter element provided within the container.

    Abstract: Silicon carbide particulate reinforced aluminum alloy matrix composites are formed using techniques which include agitation of a melt of aluminum alloy, containing magnesium, and silicon carbide particulates in a manner whereby the silicon carbide particles are maintained, during agitation, within the body of the melt; the agitation, which involves shearing or wiping of the particles in the liquid, is carried out under vacuum; and may involve incorporation into the melt of an additional amount of magnesium such that that amount compensates for the amount of magnesium which segregates to the carbide surfaces, and is sufficient to effect strengthening of the resulting composite. Aluminum alloy matrix composites, containing copper, are produced using similar agitation and mixing procedures, with the copper being incorporated in such a way as to discourage reaction between the copper and SiC particles.
