Enhancing mechanical strength of materials has been of great interest worldwide by introducing second phase reinforcement particles into the metal composite. Researchers across the world have applied this method to improve the mechanical properties of the composite, such as elastic modulus, tensile strength, compression strength, bending strength, toughness, and hardness. A highly desirable output was achieved by the above research effort, although the development of cost effective manufacturing techniques of metal composites is still an unsolved problem. In this research paper, we focus on searching new reinforcing materials as nano fillers in composites of vital importance. To improve the role of "nano fillers" as new reinforcing particles, some of the key features must be considered during the manufacturing process to further improve the mechanical strength of the material. These include surface and high aspect ratio, strong binding property with metal matrix after inclusion, homogeneous dispersion of reinforcing particles in the matrix to further avoid agglomeration. The whole process should also be cost effective. With the above approach, many types of reinforcing nano-inclusions, such as ceramic nanoparticles, nano fibers, metallic nanoparticles and carbon nanotubes have been highly exploited in effective materials engineering. This application of nanotechnology in manufacturing of improved metal composites with high mechanical properties is the subject of interest of this paper, which mainly needs intense research focus and has scope for further advancements in materials engineering. With the above approach, ceramic nanoparticles, nano fibers, metallic nanoparticles and carbon nanotubes have been effectively exploited as reinforcing nano inclusions.
