Homogeneous Distribution of Alumina Nanoparticles in the 6061 Aluminum Alloy via Mechanical Alloying

The efforts to improve more efficient aluminum alloys makes that researchers around the world pay attention on micro- and nano-reinforced elements. In this way, the synthesis of the suggested aluminum alloys is a very important step when considering their production. In recent years, the aluminum matrix composites synthesized by mechanical alloying, and reinforced with alumina nano-particles tends to be one of the materials that suggest to have high conditions of strength, ductility and corrosion resistant [1, 2]. In this context, it is important to mention that one of the main parameters to consider in the addition of reinforcing elements is the reinforcement homogeneous distribution that conferes to the material their excellent mechanical properties [3]. This research work deals with the steps to follow in order to obtain a homogeneous distribution of alumina nanoparticles in the aluminum matrix composites, where images depicted the good results obtained. At the beginning, aluminum powders were obtained from the machining process of a commercial alloy 6061 in the form of metal chips and mixed with 5.0
