The scanning data of the primaryα-Al phases and the eutectic phases of the CC and the CDS（Fig.7）samples are shown in Table 3.It is discernible that the amount of Al atoms decreases gradually from the center of the primaryα-Al phases to the eutectic phases，whereas the contents of Zn，Mg，and Cu atoms increase gradually from the center of the primaryα-Al phases to the eutectic phases.Moreover，the contents of Zn，Mg，and Cu atoms in the eutectic phases of the CDS sample（point D1）are found to be higher than those in the eutectic phases of the CC sample（point D）.However，at the center of the primaryα-Al phases，the amounts of Zn，Mg，and Cu atoms in the CDS sample（point A1）are lower than those in the CC sample（point A）.Furthermore，at the boundary of the primaryα-Al phases，the contents of Zn，Mg，and Cu atoms in the CDS sample（point C1）are higher than those in the CC sample（point C）.
