Abstract The liquidus of the Al-rich corner in the phase diagram of Al-Mg-La system has been investigated by means of thermal, metallographic and X-ray diffraction techniques. The composition of all samples was determined accurately by chemical analysis. It was found that the pseudo-ternary system Al-Mg_5Al_8-LaAl_4 is of the ternary eutectic type. There are three surfaces corresponding to the primary crystallization of a-Al, Mg_5Al_8 and LaAl_4 respectively, and three univariant lines related to the secondary crystallization. The temperature of the ternary eutectic, composed of 11.3 wt-% La, 62.9 wt-% Al and 25.8 wt-% Mg, was determined to be 445℃.
