ANALYSIS OF MECHANICAL AND MICRO STRUCTURAL BEHAVIOUR OF AL BASED METAL MATRIX COMPOSITE REINFORCED WITH BALL MILLED NANO PARTICLES: A REVIEW

In recent years Metal matrix composites have been considered as one of the most important materials which offer excellent wear resistance and stiffness, low weight, economic and high strength to weight ratio. Metal matrix composites (MMCs) reinforced with ball milled nano particles ,also called metal matrix ?nano composite, are spreading rapidly in worldwide due to their various demands in the field of engineering and science like automobiles, aerospace, energy, defence, materials, electronics and bio technology. Ball mil ling is a technique of production of nano particles and can enhance the base material in terms of damping properties, mechanical strength, wear resistance and prevent from clustering.
