TL;DR: In this paper, the grain structure, dislocation density and second phase particles in various regions including the dynamically recrystallized zone (DXZ), thermo-mechanically affected zone (TMAZ), and heat-affected zone (HAZ) of a friction stir weld aluminum alloy 7050-T651 were investigated and compared with the unaffected base metal.

Journal ArticleDOI
TL;DR: In this article, the authors examined the microstructural evolution in selected aluminium alloys based on commercial age hardenable 2000, 6000, and 7000 series alloys and showed that the nature and kinetics of the precipitation process depend on the solute-solute interactions that produce solute clusters.

TL;DR: In this article, a semiquantitative theory has been developed for the formation of precipitate free zones at grain boundaries and the results have been used to develop a model of nucleation by vacancy/solute atom clusters.
