Fabrication and characterization of Al2O3–TiC-reinforced aluminum matrix composites

Abstract

With a wide range of applications, aluminum matrix composites (AMCs) play an important role in many of the engineering applications and industries, i.e., automobile and aerospace. AMCs are the composites having aluminum as matrix and ceramics or some other metals as reinforcement. The aim of the present study is to develop the Al2O3–TiC-reinforced AMCs and study the effect of reinforcements on the mechanical properties. In the present case, the Al2O3–TiC content is varying in composition of (0, 5, 10, 15, and 20 wt%) in aluminum matrix, fabricated by stir casting technique. It is found that reinforced AMCs show the better mechanical properties as compared to unreinforced AMCs. Various properties which were improved include tensile strength, hardness, and wear resistance. It is expected that the present composite will be useful for developing lightweight aerospace components.
