Abstract
Metal Matrix Composites are technologically advance material identified in recent era as a substitute for traditional engineering materials because of their excellent properties. Out of the available material, demand for Aluminium Matrix Composites are increasing in the sector of aerospace, automobile and defense applications. The Aluminium Matrix Composites are majorly accepted because of their excellent physical and mechanical properties. There are various manufacturing techniques developed for the fabrication of AMCs. High energy ball milling is a one of the most effective and versatile routes for fabrication of nano aluminium powder. The Al powder of 99.55% purity was taken for experimentation. The 60gm of Al powder was taken in stainless steel vial with BPR as 5:1. The stainless steel balls of diameter 4mm was used as a grinding media. The ball milling was performed at different speed and time in presence of 60ml toluene as process control agent. The characterization of powder particle was done with XRD and SEM. The analysis of peak were done on origin software. The optimum speed and milling time for fabrication of Al nanoparticles of size 36 nm were found to be at 250rpm and 3 to 6 hours.
