Metals that are reinforced with particles or filaments of other metals or nonmetallics provide properties that are not possible with the monolithic material.
Metal-matrix composites are capable of providing higher-temperature operating limits than their base metal counterparts, and they can be tailored to give improved strength, stiffness, thermal conductivity, abrasion resistance, creep resistance, and dimensional stability. In an MMC, the continuous or matrix phase is a monolithic alloy, and the reinforcement consists of high-performance carbon, metallic, or ceramic additions. Unlike resin-matrix composites, they are nonflammable, do not outgas in a vacuum, and ...
