摘要
This article investigated the effects of alloying additives on the impact toughness of as-cast and heat-treated 319 alloys. The results revealed that the impact energy decreases with increasing the level of Fe, Mn, and Mg additions. The aged alloys at 180 °C had a slightly increase in the impact energy compared to the as-cast alloys. The aged alloys containing combined additions of Fe–Mn and Fe–Mg displayed a similar variation in the impact energy at different aging temperatures and times. The fracture surface of the alloys was strongly controlled by the morphology of eutectic Si and Cu- and Fe-rich phases.
