Investigations on forging of low-density Mg-Li alloys

Lightweight construction plays a vital role in aerospace applications and has a direct impact on fuel consumption and payload. Here, we present our investigations on a lightweight Mg-Li-Al-Ca-Y alloy. The material was produced through lab-scale casting and formed in a two-step forging operation. The manufacturing route and the processing behaviour are discussed, in addition the microstructure as well as the mechanical properties will be shown. In conclusion, we demonstrate the capabilities of Mg alloys with high Li contents, which are promising due to their remarkably low density and high specific mechanical properties.
