Characterization of Aluminium Metal Matrix Composite : Reinforced by Silicon Carbide and Boron Carbide on Different Weight Percentage

Composite materials are superior to the straight massive materials with respect to achievable combination of strength, density and stiffness.Metal matrix composites (MMCs) based on aluminium & aluminium-magnesium alloys are excellent candidates for engineering light structure materials, and have great potential in automotive, high performance defence and aerospace applications. Crackpropagation as well as delamination along to the interface are two major failure modes of the multilayered composites subjected over bending load.The compo casting method was adopted to prepare the composite due to easy and effective method for dispersion particulate. The composite microstructure is subsequently discussed with respect to grain refinement, reinforcement distribution, and interfacial characteristics.The beneficial of reinforcement is to increases in the strength, stiffness and the temperature resistance capacity and lowers the density of MMC. Such respect to achieve these properties the selection depends on the type of reinforcement, its method of production and chemical compatibility with the matrix and the following aspects must be considered at the time when selecting the reinforcement
