    Dear Experts,

    My next R&D project is to investigate different NDE method’s capability to accurately locate and size Stress Corrosion Cracks. Here is an example of how SCC can be seen by the EWI Computed Tomography system.

    Let me know if you want to collaborate on this study. I plan to use Thermography, ET, PAUT, and FMC/TFM.

    Please share your success stories on SCC detection and evaluation, as NDT methods, techniques, equipment, sensors…

    Many, many years ago we developed an RT test for very basic evaluation of SCC.
    Used a piece of tube the same diameter and WT as the boiler tubes to be tested we had 10 x grooves machined longitudinally on the inside of the tube.
    That tube was then x-rayed.
    The reference graph then gave us 10 x different densities based on the different groove depths to compare with the depth of the SCC seen in the subsequent radiographs taken in the boiler.
    I know my story is of no help as you are talking about very advanced techniques, just thought I would share.
