Abstract

Effects of 2 mass% Li addition on the AZ80 Mg alloy are investigated, including crystal structures, mechanical properties and corrosion resistance. Experimental results show that the density of AZ80 Mg alloy can be reduced to be 1.71 g/cm³ by addition of 2 mass% Li. Both the AZ80 and AZ80-2%Li Mg alloys exhibit the two-phase microstructure with α and β phases. Adding 2 mass% Li to AZ80 Mg alloy can obviously increase the ductility and impact toughness, but reduce the corrosion resistance.
