Due to their low density and high specific properties, the interest in magnesium Mg alloys for lightweight structural applications has steadily increased over the last decade. Nevertheless, their use remains limited due to poor room temperature ductility, low elastic modulus, and poor performance at elevated temperature. Recently, however, the use of nano-sized reinforcements has resulted in appreciable improvements in the performance of Mg alloys at both ambient and elevated temperatures. In an effort to provide a brief introduction into Mg-based nanocomposites, this report surveys the current state of research in these materials. The report begins with a review of the two major processing methods used to produce the nanocomposites. Next, the impact of nanoreinforcements on a broad array of mechanical and physical properties is discussed. Of particular interest in this section is the influence of nanoparticle type and processing method on tensile. The report concludes with some observations regarding the potential use of these materials in Army-related applications.
