Abstract
Stability and durability of magnesium die castings at elevated temperatures and dynamic loads characteristic, for example, of automotive applications are mainly limited by an insufficient resistance of the most widespread Mg-Al-Zn and Mg-Al-Mn alloys to creep and stress relaxation. In this review the effect of various die-casting parameters on the microstructure and mechanical properties of these alloys was evaluated. Porosity, casting temperature, slow shot rate (pre-fill phase) and fast shot rate or injection rate exert the most significant effect on tensile and viscoelastic properties.
