The present invention relates to the formation of metal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot of matrix metal is surrounded by a permeable mass of filler material. An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material, at least at some point during the process, which permit the shaped ingot of matrix metal, when made molten, to spontaneously infiltrate the surrounding permeable mass of filler material. After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot of matrix metal.
