Abstract

The early stages of nucleation and growth of Guinier–Preston zones in Al –Zn –Mg and Al –Zn –Mg–Cu alloys are investigated by in situ synchrotron X-ray small-angle scattering. The in situ synchrotron measurements enable to follow the decomposition kinetics from about 2 minutes after quenching. Based on the measurement of the radii of gyration and integrated intensities, three distinct kinetic regimes are observed and discussed.

Keywords: Guinier–Preston zones; Aluminium alloys; In situ small-angle X-ray scattering; Synchrotron experiment
