Abstract

A mechanically alloyed mixture of Al-1 wt.% nano-alumina (n-Al2O3) composite powders was produced using a planetary ball milling machine. Different milling times were applied to investigate the effect of milling time on the dispersion and microstructure of n-Al2O3 particulate reinforcement within the aluminum matrix. A good homogeneous dispersion of n-Al2O3 particulates was observed after 8 h of milling. Longer milling times had no significant effect on the dispersion and morphology of n-Al2O3 particulates within the aluminum matrix because a steady state had been reached.
