ABSTRACT:
The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, a suitable matrix metal, typically in a molten state, is in contact with a suitable filler material or preform in the presence of a suitable reactive atmosphere in a sealed impermeable container, at least at some point during the process, which permits a reaction to occur between the reactive atmosphere and the molten matrix metal and/or filler material or preform and/or impermeable container, thereby causing molten matrix metal to infiltrate the filler material or preform due to, at least in part, the creation of a self-generated vacuum. Such self-generated vacuum infiltration occurs without the application of any external pressure or vacuum.
