For Li-containing Mg alloys of the AZ-series, several types of IMPs were reported in the literature: Mg17Al12, MgxMey, and AlzMew (Ме are Li, Mn, Zn) . The formation of the latter two phases is more probable since the affinity of Li to Al and Mg is higher than that of Al to Mg. Moreover, Mg17Al12, AlMn, and AlMnZn IMPs typical to the AZ-series alloys have cathodic behavior towards the alloy matrix, while AlzLiw IMPs have anodic behavior . There are several reports on the effect of Li concentration on the corrosion resistance of Mg alloys . At low amounts, Li does not significantly affect the corrosion rate , however at high concentrations, it intensifies local selective dissolution of IMPs and alloy matrix phase .
