small specimen sampling

small specimen sampling

small specimen sampling

(OP)
Hi!

I would like to help me in a very hard question!
I care about the in-situ samll specimen sampling in operating systes (like pressure vessels etc.)
My question is, how we can remove a small specimen from the surface without damage both of the parental material and the specimen.
Have any idea anybody?

The other problem is how to test them? Is tehere a normalized factor to compare the normal sized specimen test results with the small specimen test result?

Thank you!

RE: small specimen sampling

What sort of testing do you need to do once you have your sample?

for example tensile test, compact test, small punch test. i know what kind of tests are in use, but the speimens aren' t standard sized, so we need a factor to correlate the results. i read that there is a different between #1200 polished and mirror polished specimens or the lubricant and non-lubriant specimens.
