| Abstract: | Compositions and microstructures of a large ZL205A casting were studied.The results showed that there exists serious segregation of Cu in the large ZL205A casting and Cu contents of part area exceed the upper limit. After heat treatment,the remelted eutectic phases of serious segregation area on the lower surface of the casting are of triangle shape,which are the oxide of Cu and Al. |
