Alloys with various contents of Li were studied by means of differential scanning calorimetry (DSC), transmission electron microscopy (TEM) and energy dispersive X-Ray microanalysis (EDX).<br />The TEM investigations revealed that three different types of precipitation are formed in the alloy matrix during artificial aging. Two of the types represent different morphologies of Mg<sub>2</sub>Si precipitates. The appearance of the third type, identified as the δ-Al<sub>3</sub>Li phase, shows that the Al-Mg-Si system can be used successfully for designing an Li-containing casting alloy. However, this alloy has not yet been developed.
