Mg-5Al-0.4Mn-xRE (x = 0, 1, 2, 3 wt.%) magnesium alloys were prepared successfully by casting method. The microstructure was investigated by light microscopy. The influence of rare earth (RE) elements on the area fraction of eutectic was analysed. The obtained results revealed that the as-cast Mg-5Al-0.4Mn alloy consist of \alfa - Mg matrix and eutectic \alfa + \gamma (where \gamma is Mg17Al12). However, while rare earth elements were added to the Mg-Al type alloy, Al11RE3 precipitates were formed. The amount of the Al11RE3 precipitates increased with increasing addition of RE, but the amount of \gamma - Mg17Al12 decreased.
