The aging phenomena in an Al-10%Mg alloy at room temperature has been investigated using mechanical properties, electrical resistivity measurement, neutron diffraction and high resolution electron microscope. The mechanical properties as the proof stress and elongation change gradually over a period of several years at room temperature. The electrical resistivity increases at the beginning to show resistivity maximum, subsequently decreases gradually with aging time. It was shown in TEM investigations that modulated structures were formed along the <100> direction in the early stage of aging, which later developed continuously into spherical G. P. zones having Ll2 ordered structure. The ordered G. P. zones, even if formed in the long-term aging, dissolve immediately by heating at 150°C.
