Fabrication and Characterization of Aluminium Based Metal Matrix Composites : A Review

Mechanical Engineering

Metal matrix composites (MMCs) are most promising material of recent interest because of its ability to meet engineering applications. Now a days ,a wide range of aluminium based MMCs are commercially used in aerospace industries and automobile sectors . Aluminium metal matrix composite exhibits favourable mechanical and micro structural properties. An effort has been made in this research work to highlight the major improvements in mechanical behaviour of Al based MMCs by varying the proportions of reinforced particulates. Meanwhile, it is found that the favourable change in properties is restricted up to an optimum limit of reinforcement addition in aluminium matrix. A comparative analysis is made over Al alloys and its MMCs synthesized by different reinforcement material including non-metallic and ceramic particles like molybednum disulfide (MoS2), titanium diboride(TiB2), zirconium dioxide(ZrO2), silicon carbide (SiC), alumina (Al2O3), boron carbide (B4C), graphite, fly ash etc.This research work summarizes the most optimised ratio of reinforcements to be done in order achieve a best version of Aluminium based MMCs.
