Type IV Creep Cracking - Images
(OP)
Does anyone have actual metallographic images of this type of cracking. I've got a failure analysis I am working on that is not creep related, but someone got it in their head that it is Type IV creep cracking and I would like an image to show how what we have is completely different from what is Type IV.

Your best bet is to search for technical papers that describe Type IV creep damage. You might want to try the web site below for starters;

I will search my library and see if I can direct you to several papers on this subject.
