Method of forming a metal matrix composite body by a spontaneous infiltration technique

The present invention relates to the formation of a metal matrix composite body by a spontaneous infiltration technique. Particularly, an infiltration enhancer and/or infiltration enhancer precursor can be positioned at least partially between or at an interface between a matrix metal (2) and a fill...

description The present invention relates to the formation of a metal matrix composite body by a spontaneous infiltration technique. Particularly, an infiltration enhancer and/or infiltration enhancer precursor can be positioned at least partially between or at an interface between a matrix metal (2) and a filler material (3) (or preform) which is to be infiltrated by molten matrix metal (2). Moreover, at least at some point during the process, an infiltrating atmosphere may be in communication with the filler material or preform (3) and/or matrix metal (2).
