It has recently been presented a thermodynamic model for the calculation of the latent heat during solidification modeling with emphasis on its evolution in the mushy zone. The calculations were applied to Lead-Tin alloys and the results were in good agreement with experimental data. These calculations are now extended to binary aluminum alloys such as Aluminum-Copper, Aluminum-Magnesium, Zinc-Aluminum and Nickel-Zirconium in a range of concentrations. The results show similar behavior of the latent heat as observed in Lead Tin alloys that is, with a larger amount of latent heat being released at the beginning of the alloy solidification. In the present report these results are presented and discussed.
