During the past ten years, the use of magnesium castings in the automotive and electronics industries has been expanding at an impressive rate. Die casting is one of the most effective fabrication methods and has been extensively used to produce magnesium components, especially in the automotive industry. However, the number of available Mg-based alloys for die casting is very limited. Therefore, it is pressing to develop some new Mg die casting alloys with good creep resistance, acceptable castability and low cost. Mg-Zn-Al (ZA) is a promising alloy system which is able to meet the requirements. But up to now, only a small amount of research has been carried out on this system. The aim of the present work is to examine and evaluate the microstructural features, tensile properties and creep resistance in order to get a better overall understanding of alloys of this system and to identify the most promising compositions. The influence of small additions of Ca and Sr on the tensile and creep properties of ZA alloys was also investigated.
