| Description | The phase equilibria of the Al-Ge-Mg ternary phase diagram were experimentally studied at the temperatures of 250, 300, 400 and 450 degrees C. The ternary phase tau (Al2Ge2Mg) suggested by the earlier structural study was found to be stable at all temperatures studied. Detailed study of the phase equilibria containing the tau (Al2Ge2Mg) phase in the ternary system have been carried out. The average composition of this phase was found to be 36 at.% Al-36 at.% Ge-Mg. In contrast to the previously published binary Ge-Mg phase diagram, the solubility of Mg in Ge was found to be within a few atomic percent. It was also found that GeMg2 intermetallic phase dissolves only small amount of Al but there is significant nonstoichiometricity with respect to the Ge/Mg ratio especially for lower annealing temperatures. |
