Abstract
The microstructures and corrosion behaviors of three Mg–Li–Al alloys are systemically investigated by changing the Li concentrations. The Al addition in the Mg–Li–Al alloys with different Li contents results in various intermetallic compounds: the AlLi formation in the Mg–3Li–6Al alloy as well as the AlLi and MgLiAl2 formation in the Mg–9Li–6Al and Mg–15Li–6Al alloys. The formation of AlLi and MgLiAl2 intermetallic compounds plays a significant role in the improvement of corrosion properties . The corrosion performance of the cast LA36, LA96, and LA156 samples can be ranked as LA96 > LA156 > LA36.
