The phase decomposition process of dilute Al-Zn binary alloys aged at 274 K was investigated by means of the small-angle X-ray scattering (SAXS) method. Structural parameters such as radius of gyration Rg, integrated intensity Q, etc. were obtained from the scattering intensity for each specimen. It is found that the aging process at 274 K can be divided into three stages, I, II and III for all specimens studied here. In stage I, where the phase dicomposition developes, Rg lay between 0.3 nm and 0.6 nm. In stage II corresponding to the coarsening process, the 1/3 power law on Rg vs time was observed. Rg lay between 1.5 nm and 2.5 nm in stage III, where slowing down of the coarsening occurred. The scaling rule was successfully applied to the scattering intensity in stages II and III. From the discussion about the scaling behaviour on the basis of two-phase model, the half width of scaled structure function was pointed out to increase depending on volume fraction.
