For the curious, the name of this blog is inspired by the term stress corrosion cracking (SCC), not from your humble host wigging out under duress. :)
(I just thought "stresscrack" sounded cool.)
SCC's a fairly common problem in materials science and nondestructive evaluation, e.g. do a quick search for 6351-T6 and you'll see some effects of SCC. Technically these SCUBA / SCBA ruptures are said to fail because of a different phenomenon, but when you boil it down it's virtually the same thing.
(By the way, if you have 6351-T6 aluminum bottles in your garage, do yourself a favour and pitch 'em. Please.)
SCC's a major issue with oil and gas pipelines too, in fact the Holy Grail of MFL inline inspection (ILI) tools is SCC detection. SCC tends to be very fine and spidery and not easily detectable by MFL; ultrasonics and Remote Field Eddy Current technologies usually have a little more success.
So now you know.
