microstructures on the mechanical properties of the alloy at both room and elevated temperatures is also investigated. By comparing the microstructures and mechanical properties of the cast eutectic Al-Cu-Si alloys with the conventional Al-Si alloys, the results show that refined microstructures with finely dispersed Ni intermetallic particles are formed in the as-cast Al-Cu-Si alloys that impact on the elevated temperature (200-300°C) properties of the alloy.
