| Abstract: | Improved rheocast process was studied for performing the high quality of Al alloy casting made of the preparation of the metal slurries. The measures taken for reducing the porosity of die casting have been investigated. It was shown that the conventional diecasting is not to be compared with the rheocasting for ZL104 and ZL702 as well as other Al alloys. The hydrogen content may be much lowered, and the bulging surface on the casting may be much improved after heat treatment. |
