摘要：

The solidification behavior of the AA6111 automotive alloy has been investigated by thermal analysis, metallographic examination in combination with thermodynamic prediction. The alloy contains a number of phase constituents and a series of reactions occur over a wide temperature range during solidification. In this paper, the freezing range, the reaction paths during solidification and the phase constituents in the microstructure were established for different cooling conditions. The solid fractions, as a function of temperature, were experimentally determined based on the cooling curves of the thermal analysis. Thermo-Gale was used to evaluate the phase prediction in the multi-component Al-Mg-Si-Cu-Fe-Mn system. The solid fractions were also calculated using the Scheil-Gulliver model. The results were compared with the experimental data.
