| Abstract: | The distribution of yttrium in Al (1 5)%Y,Al 8%Zn (1 5)%Y,Al 2%Mg (1 3)%Y and Al 8%Zn 2%Mg (0 5)%Y alloys and its effect on the cast structure of these alloys were studied. The results show that in the alloys Al Y and Al 2%Mg Y,yttrium forms Al 3Y; while in the alloys Al 8%Zn 2%Mg and Al 8%Zn,yttrium takes the form of a grain boundary intermetallic compound Y 12 Al 3Zn. In the alloy Al 8%Zn 2%Mg,the existence of yttrium also changes the distribution of zinc and magnesium. |
