Beschreibung
Zusammenfassung:	The present invention relates to novel process for forming net or near net-shape metal matrix composite bodies. Particularly, a molten matrix metal (13) is in contact with a filler material or a preform (11) in the presence of a reactive atmosphere, at least at some point during the process, which permits molten matrix metal (13) to react, at least partially or substantially completely, with the reactive atmosphere, thereby causing molten matrix metal (13) to infiltrate the filler material or preform (11) 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. The molten matrix metal (13) infiltrates the filler material (11) up to at least a portion of a provided barrier means.
