Abstract

The process of reversion of Guinier Preston (GP) zones formed during long room temperature aging was investigated on an Al-3. 2Zn-2. 2Mg alloy at 60 to 200 C. The volume fraction, mean volume, and mean size and density of the GP zone and eta prime transition phase particles were obtained by evaluation of small angle x-ray scattering data. The energy required for dislocations to move through the particles of the second phase was obtained by direct comparison of yield strength changes with the volume fraction and particle size of zones and the eta prime phase.
