Aluminum matrix composites (AMCs) have the potential to offer desirable properties, including low density, high specific strength, high specific stiffness, excellent wear resistance and controllable expansion coefficient, which significantly use for numerous applications in aerospace, automobile, and military industries. In this work, Al6061/Al2O3 nanocomposites with different Al2O3 weight percent 0.5, 1 and 1.5 wt. % were fabricated by developed stir casting process. The nanocomposites were then extruded at 550 °C. Fracture surface results show that in as-cast state, composites represent interdendritic fracture mode while in extruded condition represent a mixed mode including ductile and brittle fracture.
