  Temperature-enthalpy curves of AC2A and AC8C aluminum base and FCD500 ferrous multi-component commercial alloys were calculated based on thermodynamic calculation using the ThermoCalc for nonequilibrium state with limited diffusion in solid. Phase transformation kinetics during eutectic solidification was also taken into account for calculating the temperature-enthalpy curve of FCD500 cast iron. Heat transfer simulations during the solidification of the alloys based on the enthalpy method were carried out using the calculated temperature-enthalpy curves. Thermal analysis experiments of the alloys were carried out and measured cooling curves were compared with simulated ones. The simulated cooling curves obtained with the nonequilibrium state showed similar shape with those obtained in the experiments..
