Title:
Production methods for metal matrix composites
Document Type and Number:
WIPO Patent Application WO1991018122
Kind Code:
A3
Abstract:
The present invention relates to a novel process for forming metal matrix composite bodies. Particularly, an infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are in communication with a filler material or a preform, at least at some point during the process, which permits molten matrix metal to spontaneously infiltrate the filler material or preform. Such spontaneous infiltration occurs without the requirement for the application of any pressure or vacuum. The molten matrix metal is provided in a unique manner which enhances the spontaneous infiltration process.
