  ABSTRACT: In this investigation, the effect of aging on the hardness and tensile behavior of 15% SiCp/8011 Al composites has been studied. The composites were manufactured through stir casting method. Cast ingots of the composites were hot extruded at 500°C. The composite samples were solution heat-treated at 530°C for 3 h and quenched in cold water. The aging temperature was 130°C, 150°C, 170°C, 190°C, and 210°C for aging duration of 1, 3, 5, 7 and 9 hrs respectively. The mechanical properties measured included: tensile strength, yield strength and hardness values. The composites produced exhibited maximum mechanical properties at peak aged condition. These increases in mechanical properties during aging are attributed to the formation of coherent and uniform distribution SiC particles in the aluminum matrix composites. It was also observed that thermal modification plays an important role in retaining the ductility of composites. This result shows that a substantial improvement in mechanical properties has been achieved in the reinforced metal matrices produced after age-hardening.
