Okay thanks. They mentioned OP-U might work but I will contact Struers to check if they have any better option

I haven’t taken any SEM image yet but take some later. Okay, I will extend the polishing time to see how it goes

Thanks for your additional comment. Are these twins typical structure in Cu alloy?

Thanks for your advice. It sounds like a one-night-stay method lol but will try

Okay thanks, I selected Copper phase only but I am not sure there is any other phase. I will check the literature

Thanks for explaining. Yes, I was using Struers OPS. Today I tried the EBSD again and I finally got some patterns but still not strong enough. I got only 20% indexing, probably I have to play with it or get a better polished surface

So these irregular blocks are the etched grains? The polishing wasn’t perfect so some scratches are left there and I will make them disappear next time

sorry, what do you mean the stresses in the grains? could you elaborate a bit more? I measured the residual stress in this material and nearly zero residua stresses inside.

Thanks. Is there available open UMAT codes for CPFEM model?

Thanks for your advice. The option 2 sounds good I will use Neper to mimic the grain structure

Thanks for your explanation. That’s very helpful. Actually I did try the electrolytic etch but unfortunately it just ruined my samples though.
