Abstract
A metal matrix composite (e.g. of SiC in a metal alloy) is made by the steps of atomizing a stream of molten metal to form a spray of hot metal particles by subjecting the stream to relatively cold gas directed at the stream, applying to the stream or spray relatively cold solid particles of a material of different composition from the metal, and depositing the metal having the particles incorporated therein. The deposit is made into a shaped metal matrix composite by reheating it to a controlled temperature substantially above the liquidus of the metal at which it flows under pressure and casting the fluid deposit to give the shaped product.
