Abstract

Nano particulates reinforced metal matrix composites are very promising materials compared to micro sized particulate composites, which possess superior strength, ductility and wear resistance. Nano composites are very useful in many automobile and aerospace applications. The metal matrix composites are filled with Nano particles will vary the mechanical and physical properties of the material compared to those of the matrix. The Nano particles can improve the properties of base material in terms of mechanical strength, wear resistance, toughness, fatigue life and damping properties. Predominantly different kinds of metals like Al, Mg, Ti, Zn and Cu are employed for the production of composites with the reinforcement of Nano particles such as graphite, Al2O3, SiC, B4C, TiC, Si3N4 as well as carbon nano-tubes. The main drawback for the synthesis of these metal matrix composites is that the low wettability of the reinforcement phase by the molten metal, it is not possible synthesis by conventional casting techniques. In literature several other techniques for the production of Nano-composites are available. The present work is aimed at reviewing the synthesis of bulk metal matrix Nano composites, the important techniques in manufacturing and a review of improvement of Nano-reinforced metal matrix composites mechanical properties and the applications.
