Aluminium alloys that are strengthened by alloying elements in solid solution may present a particular sensitivity to intergranular stress corrosion cracking as a result of intergranular dissolution. In Al-5Mg alloys such as AA5083, precipitation of the β-phase (Al3Mg2) at grain boundaries strongly favours intergranular fracture. Previous experimental studies revealed that local plasticity seems to play a significant role in crack initiation. Nevertheless, the exact role of crystal plasticity in the vicinity of grain boundaries is not well understood. The main goal of this doctoral thesis is two-fold: (i) to study the role of the local stress and strain fields on the mechanism of intergranular stress corrosion cracking and, based on such un...
