Introduction

Abstract

Metal matrix composites (MMCs) consist of at least two chemically and physically distinct phases, suitably distributed to give properties not obtainable with any one of the phases individually. Generally, there are two phases, say, a fibrous or particulate phase distributed in an appropriate manner in matrix. Examples include continuous alumina fibers in an aluminum matrix composites used in power transmission lines, Nb--Ti filaments in a copper matrix for superconducting magnets, tungsten carbide (WC)/cobalt (Co) particulate composites used as cutting tool and oil drilling inserts.
