Abstract
In this study, a computer-aided instrumented Charpy impact test was used to produce the load–time information in addition to data concerning the energy absorbed of unmodified and Sr-modified cast automotive Al alloys. The total energy was used to discuss the impact properties of the alloy with respect to the different alloying elements and melt processing parameters. Effects of alloying elements, Sr-modification, and cooling rate were specifically evaluated. Aging response of the Al alloys at 185 °C indicated a rise in hardness and decline in impact toughness during the first 4 h of aging. The cooling rate is found to have a direct effect on the size and distribution of microstructural phases in a casting, and in turn, on the impact toughness as well.
