摘要：

The creep behavior of die cast magnesium alloys is examined for the high temperature alloys AE42 and MEZ. Creep behavior in these fine-grain die castings is dependent on the stability of the near grain boundary microstructure and is improved by rare-earth element additions and reductions in aluminum content.
