Atomic structures of precipitates in Al–Mg–Si alloys with small additions of other elements

In this work metastable precipitates formed in an Al–Mg–Si–Cu–Ag alloy have been imaged by probe C s corrected HAADF–STEM and the distribution of Ag and Cu atomic columns has

Bonding energies and volume misfits for alloying elements and vacancies in multi- component Al-Mg-Si alloys have been calculated using density functional theory and the results

h 1 precipitates in Al–Zn–Mg alloys and b ′ 1 precipitates in Mg–Zn alloys of high-aspect ratio and flat precipitate/matrix interfaces are built up solely by C14 stacking of the

F I G U R E 7 Optical microscopy images of the cross ‐ section of the AA6005 and model alloys after 10 – 120 h of immersion in the accelerated intergranular corrosion test

Considering the ADF STEM image in figure 5a, in which the precipitate has likely been sheared by a sin- gle dislocation close to the specimen surface (and possibly more times

For alloy S, the precipitates typically showed a predominantly Al-Mg-Si containing β″ phase and U2 phase interior, and some Cu enrichment, as well as a few sub-units of β Cu ′

We have shed light on some important findings regarding the muon trapping in the materials and its interpretation in terms of (sub-)nanometer- sized defect content. In particular,

This is clearly lower than the calculated 25 MPa that our S1 devices experienced without noticeable plastic deformation (although in accord with the C1 situation). The 25
