Abstract

The reinforcement of Aluminum alloys opens a wide range of industrial application for
these alloys in areas where reduction of weight has first priority, in General this operation
known as metal matrix composite (MMC). In this study the nanocomposite material were
fabricated using stirring time for 6 minutes at 450 rpm stirring speed .Al-7075 alloy was the
base metal and the reinforcement nanocomposite material was the Alumina Al2O3 of 10
nanometer in grain size , which is used as weight percentage (wt%) for 0.3,0.5,0.7 wt%
Al2O3. The results show that the best enhancement in fatigue life and strength were occurred
at 0.3 wt% of Al2O3.
