The aim of this work is preparing and studying some of mechanical properties [Brinell
hardness (BHN) and compression strength] of aluminum matrix composite material that reinforced by
(3, 6 , 9 , and 12 wt.% ) Al2O3 particles. Powder technology technique is used in samples preparing.
Samples were compacted by using single action pressing then followed directly by sintering process at
500°C under the effect of inert gas conditions
Results were showed an advancing in the Brinell hardness (BHN) and compression strength
especially at 12 wt.% ?- Al2O3. The development in the Brinell hardness (BHN) and compression
strength were found to reach 89% and 54% respectively from the initial properties of unreinforced
aluminum samples.
