Evaluation of Mechanical Properties of Aluminium Alloy …

The mechanical properties of metal matrix composites like tensile strength and hardness tests were carried out. Wear test was also performed using pin on disc. In the presence of silicon dioxide and fly ash (0–10%) with aluminium matrix, it was fairly observed that the densities of the composites were decreased and the hardness was increased.
