ABSTRACT:
A method is provided for preparation of a composite including steps of providing a preform and a liquid infiltrant alloy including at least two elements and having a liquid infiltrant alloy composition which is selected so that the liquid infiltrant alloy spontaneously infiltrates the preform and contacting the liquid infiltrant alloy with the preform so that a chemical reaction occurs to form a composite by reactive infiltration, as are composites produced according to the method of the invention.
