| Abstract | In this work, synchrotron-based small-angle X-ray scattering technique was used for in situ tracing the evolution of microstructure parameters (including precipitate mean size, volume fraction and number density) during retrogression and reaging (RRA) treatments of an Al-7.5Zn-1.7Mg-1.4Cu-0.12Zr alloy. The mechanical and electrical properties of the alloy during RRA have also been investigated. The results show that the retrogression is characterized with a rapid dissolution stage at almost constant average precipitate size, followed by a coarsening stage with increasing precipitate size and volume fraction. The reaging treatment not only brings the re-nucleation of g0 precipitates, but also keeps the size of the existing precipitates to a reasonable value. The developments of the mechanical and electrical properties of the alloy during RRA have been discussed based on the microstructure evolution. (c) 2013 Elsevier Ltd. All rights reserved. |
