Preparing and studying some mechanical properties of aluminum matrix composite materials reinforced by Al2O3 particles

الملخص EN

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.

% α- 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.
