Effects of samarium addition on microstructure and mechanical properties of as-cast Al-Si-Cu alloy

The effects of rare earth samarium (Sm) additions on the microstructure and mechanical properties of as-cast Al-Si-Cu alloy were investigated by optical microscopy and scanning electron microscopy (SEM). The results show that Sm can effectively refine the α(Al) dendrite and the eutectic silicon. In...
