Due to some recent failures of a spun grey cast iron water mains (due to graphitic corrosion from both internal and external surfaces) I would now like to determine the mechanical properties of the pipe material. This information would then be used to assess the critical flaw size and potential...
I have a sample of aluminium (6061-T6) that has a hard, highly adherent matt grey coating on both surfaces. I need some method of identifying the coating type. Any ideas?
What I know so far is
-The coating remains intact/adherent during a tensile test
-coating is harder than the aluminium...
This is sort of a two part question.
At what temperature does copper begin to experience rapid oxidation in atmospheric conditions? Is this temperature related to the type of oxide being formed? (eg CuO vs Cu203).
On a separate issue, has anyone come across branching transgranular type cracking...
