Abstract

The hardness and tensile behaviors of aluminum matrix composites reinforced with nanometric Al₂O₃ particulate have been found to increase with the volume fraction of the reinforcement. Above 4vol.% of Al ₂O₃, however, the strengthening effect leveled off because of the clustering of Al₂O₃. The main strengthening mechanism was Orowan strengthening of effective nano-Al₂O₃ particles evenly distributed in the matrix.
