In the metal casting industry, an improvement of component quality depends mainly on better control over the production parameters. In order to gain a better understanding of how to control the as-cast microstructure, it is important to understand the evaluation of microstructure during solidification and understanding how influence the changes of chemical concentration on this microstructure. In this research, the effect of Cu content on the microstructure and solidification parameters of Al-Si-Cu alloys has been investigated. Thus, the thermal analysis of the alloys is used to control of aluminum casting process. The effect of different Cu content on solidification parameters such: aluminum dendrites nucleation temperature (TLiq, Liquidus temperature), á+â eutectic nucleation temperature (TE(Al+Si)N), Cu-rich eutectic nucleation temperature (TAl+Cu), solidus temperature (Tsol), solidification range (ÄTs) has been studied in liquidus region. Influence of Cu content on the microstructure has been carried out. The principle observation made from this work ware that as copper concentration is increased the liquidus and solodius temperature decried. In addition to this it was observed that increase a Cu content from 1 to 4 wt % caused reduce of the secondary dendrite arm spacing and increase the grain size.
