Notes:
Regardless of whether it is cast microstructure, the grain structure that is the product ofthermomechanical processing or the nanoscale dispersions of strengthening second-phase particles,it is inescapable that the structural scale that controls mechanical properties in Al alloys isdetermined primarily by processes of nucleation during either solidification, recrystallisation orsolid-state phase transformation. In those advanced alloys with bulk amorphous or nanocrystallinestructure, production of an amorphous precursor is reliant on initial suppression of the nucleation ofcrystallisation, and subsequent controlled nucleation of dispersed nanocrystals within amorphousmatrix. The processes of nucleation that control structural scale in modern Al alloys are brieflyreviewed, with a focus on potential for further structural refinement and advances in properties
