A fragment of the Al corner in the ternary Al–Ge–Mg phase diagram has been constructed. Experimental methods have shown that the tie-line of the L ⇆ α-Al + Mg2Ge three-phase eutectic equilibrium (corresponding to the maximum temperature of eutectic transformation) does not match the stoichiometric Al–Mg2Ge section in the ternary Al–Ge–Mg phase diagram and is shifted toward its magnesium-rich side. The temperature–composition parameters of the univariant L ⇆ α-Al + Mg2Ge eutectic transformation and the boundaries of two-phase α-Al + Mg2Ge alloys after crystallization and annealing have been determined. The results will be used in the development of new aluminum casting alloys.
