The effect of thermal ageing on the microstructure and properties of 10wt% and 20wt%SiC particulate reinforced Al-Si-Fe matrix composite, produced by double stir casting route, have been studied. The composite samples were solution heat-treated at 500o C for 3 hrs and aged at 100, 200, and 300o C with ageing time between 60 and 660 minutes. The ageing characteristics of these grades of composite were evaluated using hardness values, impact energy, tensile properties and microstructure.
