Abstract

Guinier-Preston zones in <(Al)under bar>-Ag and <(Al)under bar>-Cu were investigated by diffuse X-ray and neutron scattering. In Al-3 at% Ag no differences are found between zones formed above and below 500 K (epsilon- and eta-zones, respectively). Their average Ag concentration is (80 +/- 10) at%, and the Ag concentration decreases by 10-15% from shell to core of the zones. In Al-1.75 at% Cu, Guinier-Preston I zones are dominantly monolayers with a Cu fraction of (84 +/- 2) at%.
