intensifying local galvanic corrosion of such alloys . An increase in the volume fraction of the Li-containing IMPs promotes filiform corrosion along the grain boundaries and inside the β-Li phase . An increase in the corrosion rate with increasing amounts of Li was reported for Mg-Al-Li, Mg-Zn-Li, Mg-Li-Al-Zn-Y, Mg-Li-Ca, and Mg-Al-Li-Zn alloys .
