Abstract
Supersaturated solid solutions and metastable intermediate phases can be produced in the Al-Ge system by very rapid quenching from the melt. All available data on metastable phases in this alloy system are critically analyzed in this paper, taking into account the techniques of investigation, particularly the quenching methods. It is established that a maximum of about 7 at. % Ge can be retained in the solid state in aluminum by liquisol quenching. Two large tetragonal unit cells with a congruent 13 A and c congruent 12 A (for the first phase) and a equals 14. 98 A and c equals 16. 03 A (for the second phase) are shown to account for all extra reflections in x-ray patterns observed by different investigators. The formation of an amorphous alloy phase is considered doubtful.
