Aluminum Metal Matrix Composites

Hybrid composites are those composites which have a combination of two or more reinforcements in a single matrix. In this study, Hybrid Aluminum Metal Matrix Composites were fabricated by using Stir Casting technique. Hybrid composites with three reinforcements such as Aluminum oxide(Al2O3 ), Silicon Carbide (SiC) and Boron Carbide (B4C) in different proportions are considered and Aluminum alloy 6061-T6 (Al6061) as base alloy matrix. Later, the cast aluminum metal matrix composites were machined as per ASTM standards with required dimensions. Mechanical tests such as tensile, flexural, Charpy impact, Brinell Hardness tests were conducted on the composites fabricated inorder to evaluate effect of reinforcements. Morphological study of the composites is carried out by using Scanning electron microscope (SEM). The test results were studied and analyzed.

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

Aluminum Metal Matrix Composites

Metal matrix composites (MMCs) are considered as important engineering materials due to their excellent mechanical, as well as tribological properties. When the metal (or alloy) matrix is reinforced with two or more reinforcements, those composites are the so-called hybrid composites. The aluminum metal matrix composites, reinforced with silicon carbide (SiC) and graphite (Gr), are extensively used due to their high strength and wear resistance. The tribological characteristics of such materials are superior to characteristics of the matrix. This research is presenting influence of the load and the graphite and silicon carbide contents the composites’ wear rate and the friction coefficient.
