Due to the increasing demand to reduce greenhouse gas emissions, magnesium (Mg) alloys have received renewed attention as a means to reduce the weight of vehicles. However, the cast products account for most of Mg alloy usage and the most intensively studied wrought Mg alloys are those based on AZ31 alloy. Obviously, the lack of choice limits the scope of applications of wrought Mg alloy. Mg-Zn-based alloys show a pronounced age hardening response; and many alloying elements have been added into the system to improve its mechanical performance. However, the application of Mg-Zn alloys is still limited due to the high cost of rare earth alloying elements and processing technologies. Therefore, it has been a challenge to develop high strength Mg alloys with improved ductility. Previous studies at the University of Auckland have discovered a new alloy system containing a small amount of tin (Sn), lead (Pb) and zirconium (Zr), which shows very high ductility. Motivated by this discovery, the thesis project investigates the effect of alloying elements Pb and Sn addition on the microstructure and mechanical properties of Mg-Zn alloy.
