Abstract

For a decomposing Al-3 at.%Ag alloy the mismatch of Guinier-Preston zones was determined from high-resolution measurements of the diffuse X-ray scattering near the 222 Bragg reflection. It was found that the mismatch of the Guinier-Preston zones is largest directly after quenching and decreases monotonically with ageing time. In the temperature range from 110 to 200°C the rate of mismatch reduction increases with increasing temperature.
