Abstract : This research had present the preparation of bars with length of about(13cm)and a diameter of (1.5) cm of composite material with metal matrix represented by (Al-Cu-Mg) cast reinforced by (ZrO2) or (Al2O3) particles with chosen weight percentages (1, 3, 4.5, 6) wt %. The reference alloy and the composite material were prepared by casting method and using vortex technique in order to disperse reinforced particles homogeneously in the reference alloy. In addition, two main groups of composite materials were prepared depending on the type of reinforced materials, the first group included composite material reinforced by (ZrO2) particles of Particles size (25µm>p.size?0.05µm), while the second group included composite material reinforced by(Al2O3) particles of particles size (30µm>p.size?0.1µm). The study focused on the effect of solution heat treatment at (495)C° and the following forming process. Results of fatigue and hardness tests revealed an increase in fatigue resistance and hardness by addition of reinforced particles. The effect of type of reinforced particles on the mechanical properties was clearly noted. An increase in fatigue resistance and hardness of composite material reinforced by (Al2O3) particles was higher compared to the reinforced by (ZrO2) particles. Their values were more than in the reference alloy.
