Abstract: the SiC / 2024 aluminum matrix composites were prepared by powder metallurgy. Scanning electron microscopy (SEM), X-ray diffraction (XRD), tensile and hardness testing method The effect of heat treatment on the microstructure and mechanical properties and microstructure of the composite material. The results showed that: SiC particles are distributed uniformly in the matrix, a good bond with the substrate. After heat treatment, the tensile strength and hardness of the alloy are significantly improved. Strengthening phase mainly Al2Cu, in the form of particles dispersed 2024 aluminum matrix. Solution at the same temperature, the solution T6 effect than T4. <br>Keywords: SiCp / 2024 aluminum matrix; heat treatment; microstructure; mechanical properties
