Hi All
I just wanto to ask if someone has ever experienced stress corrosion on Aluminium 6082-T6 alloy. I am working on a strange problem, where I have a component made of this alloy and a breakage occurs in a zone where there is an high tensile stress (normal environment, no strange attacks or conditions present). The fracture surface is fatigue similar (there is a black pit and next some oxide waves propagating till critic section).
I had some component analyzed by a laboratory and they said this is only fatigue because they did not find any corroding attack...but in my opinion they were not sure about it !
What do you think ?
Greetings,
