Aluminum 6061 is a heat-treated, extruded alloy used for various engineering and structural components such as wings and fuselage of aircraft, railings, window frames, driveshaft and valves, etc. Al-6061 is widely used amongst its 6000 aluminum series because of its outstanding properties like medium to high strength, excellent environmental resistance, low density, high elongation at break and superior machinability. This paper aims to review the mechanical, tribological and microstructural characterization of stir cast Al-6061 metal/matrix composites (MMCs). In this review article an attempt has been made to demonstrate the effect of different reinforcements on metallurgical behavior of Al-6061 MMC. The particulates reinforcements like SiC, Al₂O₃, Gr, B₄C, TiC, fly ash, bagasse ash and red mud were dispersed with Al-6061 alloy through stir casting route as single, dual and triple reinforcements. The experimental results showed significant improvement in tribological and mechanical properties of Al-6061 MMC as compared with Al-6061 alloy. The overall characterizations of Al-6061 MMC are summarized with key findings, which will provide a methodical approach for researchers in selecting optimized parameters for the fabrication of aluminum-based MMC.

铝6061是一种热处理过的挤压合金，用于各种工程和结构部件，例如飞机的机翼和机身，栏杆，窗框，传动轴和阀门等。铝-6061由于其铝的广泛应用而广泛使用中等至高强度，出色的耐环境性，低密度，高断裂伸长率和出色的机械加工性等出色性能。本文旨在综述Al-6061铸造金属/基体复合材料（MMC）的力学，摩擦学和微观结构特征。在这篇综述文章中，尝试证明不同的增强剂对Al-6061 MMC的冶金行为的影响。颗粒增强剂，如SiC，Al ₂ O ₃，Gr，B ₄C，TiC，粉煤灰，甘蔗渣灰和赤泥通过搅拌铸造的方式与Al-6061合金一起分散为单，双和三重增强材料。实验结果表明，与Al-6061合金相比，Al-6061 MMC的摩擦学和力学性能有了显着改善。Al-6061 MMC的总体特性与关键发现进行了总结，这将为研究人员选择用于制造铝基MMC的优化参数提供一种有条理的方法。
