State of 3-D micro-damage in hydrogen redistributed regions of precharged high strength aluminium alloy
Source abstract
Abstract
Highlights / ●Micro-damage state formed in hydrogen redistributed regions of AA 7075 is revealed. / ● H-redistribution due is shown to change the content and shape of micro-pores. / ●Extended agglomerated zone is revealed for the first time near intergranular crack. / ●Embrittled damage state is shown increase micro-pore content for H-repartition. The state of 3-D micro-damage in regions of precharged high strength aluminium alloy where hydrogen redistribution is induced by thermal treatment, or deformation near intergranular fracture surface, are compared using synchrotron microtomography (SR-CT). 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.
