Abstract

Abstract Given studies have carried to produce lightweight metal matrix composites (MMC) which have good mechanical and thermal properties. An alloy of Mg/Al has considered as the most commonly used alloy in the transport, Electronics and Sports industry for the production of lightweight elements. Mg/Al alloys improve mechanical, fabrication, and welding characteristics and reduce the production cost as compared to pure metal. Mechanical and thermal properties like creep and fatigue properties, damping, stiffness and specific strength significantly improved due to the addition of reinforcement materials into the metal matrix compared with the traditional engineering materials. SiC, Al2O3, and CNTs are commonly used reinforcement material for Mg/Al metal matrix composites. CNTs have thermal conductivity (6000 w/mK), high strength (100 GPa) and low mass density (1.3–1.4 g/cm3). CNTs are the most suitable reinforcement for preparation of the lightweight metal matrix.
