| Abstract Scope |
The development of Mg-Li alloys to create ultra lightweight alloys has become popular in recent years and presents intrinsic interest from both a technologic and academic perspective. While most studies have focused on either α-HCP or duplex α+β Mg-Li alloys, little work has been performed on the development of BCC β-Li alloys which are stable at concentrations greater than approximately 10.3 wt% Li. This research explores the evolution of microstructure on the hardening response and corrosion resistance of BCC Mg-Li alloys using traditional Mg alloying elements in combination with cathodic poisons. Early results have shown that Ge is effective in improving the corrosion resistance and passivity of binary β-Li but offers little benefit to improving hardening response. The synergistic effect of tertiary and quaternary additions with Ge on mechanical behavior and corrosion resistance is currently under investigation and will be presented on. |
