الملخص

The present research dealt with the preparation of bars with a length of about (13Cm) and a diameter of (1.5Cm) of composite material with a metal matrix represented by (Al-Cu-Mg) cast reinforced by (ZrO₂) or (Al₂O₃) particles with choosen weight percentages (1, 3, 5)%. The matrix alloy and the composite materials were prepared by casting method using vortex technique in order to disperse reinforced particles in a homogeneous way on the matrix alloy. In addition to that, two main groups of composite materials, the first group included composite material reinforced by (ZrO₂) particles with by the particle size (0.05µm<p.size<25µm) while the second group included composite material reinforced by (Al₂O₃) particles represented by the particle size (0.1µm<p.size<30µm).
