Abstract: “This research work reports the effect of solidification rate on structural morphology and wear behavior of unmodified Al-7Si-3.5Cu (A380) alloy casting. Solidification rate is an important processing parameter that affects microstructural features of cast alloy, which in turn significantly influences the mechanical properties and wear behavior. It is found that morphological features of eutectic silicon and copper aluminide (CuAl2) have the substantial effect on wear characteristics of the alloy. The presence of refined eutectic silicon and CuAl2 particles in water-cooled casting remarkably reduces the Coefficient of Friction (COF)”

Keywords: Al-Si alloy casting, eutectic silicon, CuAl2 , Coefficient of Friction (COF).
