Aluminum Metal Matrix Composites

Aluminum metal matrix composites with various reinforcements had pronounced prospective of meeting the criteria of recent engineering applications like aerospace, automobile, breakpads, sports, this is due to their enhancement of some mechanical properties by some addition of matrix in to decide material. The present study focuses on the fabrication of 6351 aluminum MMC hybrid composites reinforced with silicon carbide and graphite powder, followed by a wear test for characterization of the material. Although several methods are available for the fabrication of Al-Sic MMC, we have employed stir casting technique due to its simplicity and economical. In this work aluminum metal matrix composites reinforced with different weight fractions of 2%, 4%, 6% and 8% graphite and silicon carbide in equal proportion characteristics were compared with Al6351 alloy. It is found that the wear properties have been improved with increase in weight fraction of the reinforcements of silicon carbide and graphite in aluminum matrix
