Abstract：The eutectic structure of Zn-5Al alloys as cast is investigated with optical microscope,SEM,TEM,and is analyzed with energy dispersive spectrum.It is shown that cast structure of Zn-5Al alloys is typical lamellar eutectic structure which can be expressed as β(α|β|α)β.The β outside the round brackets represents the wider lamellae in eutectic structure which are formed in eutectic reaction.The other part inside the round brackets represents narrower lamellae in eutectic structure.They are eutectoid of α and β-This β phase is covered by α phase.
