Heat due to abrasive cutting vs residual stress
Heat due to abrasive cutting vs residual stress
(OP)
Dear sirs,
Please advise me about the standard or suitable practice for residual stress specimen preparation for XRD technic.
I don't sure that normal abrasive cut-off wheel with cooling affected to this kind of measurment or not.
We anxious about quantity of heat genearated near the specimen.
Thank you for your kind support,

RE: Heat due to abrasive cutting vs residual stress
Grinding is not appropriate for surfaces that will have x-ray diffraction measurements taken. The normal process is to test the surface, then remove a small amount of material by electropolishing, say 25 micrometers, then test again. Repeat as necessary.

We did not examine on cutting surface but we will test on neighbor surface area that heat due to cutting might be affected to it.
So, i am not sure that this quantity of heat will affect to measurement result or not
Thank you for your suggestion

What alloy are you looking at? Do you have estimates of the magnitude and variation present in your sample?
I'm certain that stress relief will occur at lower temperatures than microstructural changes, in steels at least.
