Abstract
Disclosed herein is a composite comprising a metal alloy matrix; where the metal alloy matrix comprises aluminum in an amount greater than 50 atomic percent; a first metal and a second metal; where the first metal is different from the second metal; and where the metal alloy matrix comprises a low temperature melting phase and a high temperature melting phase; where the low temperature melting phase melts at a temperature that is lower than the high temperature melting phase; and a contracting constituent; where the contracting constituent exerts a compressive force on the metal alloy matrix at a temperature between a melting point of the low temperature melting phase and a melting point of the high temperature melting phase or below the melting points of the high and low temperature melting phases.
