I want to reveal the grain structure on the curved surface of a tubular sample made of stainless steel (SS 304). In the usual sample preparation method to reveal the grain structure one needs to polish the sample flat first and then etch it. But, I want to reveal grain on a curved surface of my tubular specimen (please see attached sketch) without polishing it flat.
Can anyone suggest the appropriate sample preparation method for my application? Is electrolytic polishing suitable here?
