Precipitates in a heavy pre-deformed Al-1.3Cu-1.0Mg-0.4Si wt.% alloy
The effect of low Cu additions on precipitate crystal structures in overaged Al-Mg-Si(-Cu) alloys
The Effect of Elevated Temperatures on Precipitation in Aluminium Alloys
An experimental study on pre-stretched double-chamber 6000-series aluminium profiles subjected to quasi-static and dynamic axial crushing
Automotive crash boxes require a material selection with strength and ductility in a balanced combination. In this work, the behaviour of double-chamber AA6063 and AA6082 aluminium profiles subjected to quasi-static and dynamic axial crushing was studied experimentally. The profiles were stretched...
Grain boundary structures and their correlation with intergranular corrosion in an extruded Al-Mg-Si-Cu alloy
Stress Corrosion Cracking in an Extruded Cu-Free Al-Zn-Mg Alloy
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...
Atomic structure of solute clusters in Al-Zn-Mg alloys
Scanning transmission electron microscopy imaging of Al–Zn–Mg alloys has provided new information on the atomic structures of solute rich clusters forming from a supersaturated solid solution at low temperatures. A unique unit of high Zn/Mg ratio is the fundamental cluster building block. The unit...
