A comparison of the state of 3-D micro-damage induced by hydrogen redistribution due to thermal treatment and deformation near an intergranular fracture surface is carried out in high strength aluminium alloy using synchrotron microtomography. The mapping of various types of micro-damage provides evidence that hydrogen redistribution occurs along with a change in content and shape of micro-pores. The presence of intergranular cracks and an extended agglomerated micro-pore damage state are found to be in close proximity to each other, suggesting a mechanistic relationship for both formation of the unique damage architecture and insidious manifestation of embrittlement in high strength aluminium alloys.
