Cluster evolution mechanisms during aging in Al–Mg–Si alloys
Abstract
Using Atom Probe Tomography (APT) and Phase Field Crystal (PFC) modelling, the early-stage precipitation phenomenon is investigated for naturally- and artificially-aged Al–Mg–Si alloys of two different Mg/Si ratios, i.e. 1 and 2. It is shown that, regardless of alloy composition and aging history, the earliest precipitates appear as finely-dispersed Si-rich clusters which gradually undergo a simultaneous coarsening and Mg-enrichment. In …
