| Abstract: | | 1. |
Redistribution of the silicon alloying element and impurities takes place during AL2 alloy chilling in the solidifier. This promotes stepwise changes in the eutectic microhardness across the casting section. Under these conditions, there is negligible  -solid solution microhardness variation.
| | 2. |
The AL2 alloy strength after chilling is greater than that obtained by sand or chill mold casting. This may be due to the fact that the castings obtained by chilling are dense and possess a nonuniform alloying element and impurity distribution in the form of bands that are located along the tensile loading.
