| 英文摘要 | Casting Mg-Al-Zn alloys are promising for the automotive components loaded under both high strength and high ductility, as well as under high temperatures. The relationship of compositions, phase constituents and solidification paths of casting Mg-Al-Zn alloys were investigated by SEM/EDS, XRD and thermodynamic calculations. It is shown that the phase constituents of Mg-Al-Zn alloys are related to Zn/Al ratio; with the Zn/Al ratio increasing, the secondary phase gamma-Mg(17)Al(12). It is gradually replaced by phi-Mg(21)(Zn, Al)(17) and eventually disappears completely. The phase constituents and solidification paths of the alloys under various conditions, including equilibrium, Scheil and permanent mould casting, were examined by thermodynamic calculation software Pandat with the availability of thermodynamic description of Mg-Al-Zn ternary system. The practical casting process deviates from the equilibrium; however, the practical phase constituents of the experimental alloys except ZA65 can be predicted by the Scheil model. Because of no considering the peritectic reaction in which solid participates as reactant, the Scheil model can not correctly predict the phase constituents of ZA65 alloy under permanent mould casting condition. |
