This work has investigated the effect of the combination of natural ageing and 80% pre-deformation after solution heat treatment on precipitation during subsequent artificial ageing in an Al-1.3Cu-1.0Mg-0.4Si wt.% alloy. It was found that a combined use of atomic resolution aberration corrected high...

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...

Many important properties in the Al-Mg-Si alloy system, like hardness and toughness, is to a large extent determined by the atomistic precipitate interface structure. In this work we investigate the strain field around bulk hardening β'' precipitates and the fracture decohesion at β' grain boundary...
