Stress corrosion cracking (SCC) in Cu-free Al-Zn-Mg (7xxx) aluminium alloys limits its use in many applications. In this work, we study in detail the microstructure of a peak and slightly overaged condition in an AA7003 alloy using transmission- and scanning electron microscopy in order to provide a...

The image contrast of sheared needle‐like urn:x-wiley:00222720:media:jmi12901:jmi12901-math-0001 precipitates in the Al‐Mg‐Si alloy system is investigated with respect to shear‐plane positions, the number of shear‐planes, and the active matrix slip systems through multislice transmission electron mi...

Crystal structures of hybrid precipitates have been analysed by atomic-resolution scanning transmission electron microscopy in an aged Al–Cu–Mg–Si alloy. A new unique hybrid precipitate (UHP) has been found as rod-shaped discrete particles along 100 in bulk aluminium matrix. The UHP consists of a co...

This study concerns the effect of low Cu additions (<0.1 at.%) on the precipitate crystal structure evolution in three Al-Mg-Si(-Cu) alloys during overageing. The evolution was assessed through a combination of atomic resolution scanning transmission electron microscopy, scanning electron diffrac...

Al–Mg–Si alloys are usually formed into their final shape by rolling or extrusion. After extrusion, the aluminium profiles are usually straightened, causing the material to be subjected to a small plastic deformation. This study demonstrates the positive effect on strength that can be obtained from ...
