The structures resulting from liquid-quenching and subsequent low temperature aging of Al-Mg alloys containing magnesium up to 36.8 at% were studied by transmission electron microscopy and X-ray diffraction. The L12 type superlattice Al3Mg was found to form in both 21.2 and 26.2 at%Mg alloys which had been liquid-quenched and subsequently aged at 100°C for about half an hour. The size of anti-phase domains ranges from 100 to 300 Å.
