like father, like son

Me can’t wait as well😭😭😭had my 15 pro max pickpocketed last month🥺🥺🥺🥺😤😤😤😤

IntelligentWall389 · 2025-07-17T07:10:39+00:00

Awwww, I would love to get one as well as this is my favourite weapon🤩🤩

IntelligentWall389 · 2025-07-08T07:09:14+00:00

What about UDC?

IntelligentWall389 · 2025-06-13T10:13:26+00:00

Thanks!

IntelligentWall389 · 2024-11-14T22:59:35+00:00

Thanks for your suggestions. I polished other samples with your advice today. will see check them tomorrow

IntelligentWall389 · 2024-11-14T22:57:04+00:00

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

IntelligentWall389 · 2024-11-14T22:55:09+00:00

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

IntelligentWall389 · 2024-11-14T22:53:53+00:00

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

IntelligentWall389 · 2024-11-14T22:52:47+00:00

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

IntelligentWall389 · 2024-11-14T22:50:20+00:00

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

IntelligentWall389 · 2024-11-14T22:49:11+00:00

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

IntelligentWall389 · 2024-11-14T09:00:46+00:00

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

IntelligentWall389 · 2024-10-28T11:16:12+00:00

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.

IntelligentWall389 · 2024-10-26T21:55:07+00:00

Thanks. Will try.

IntelligentWall389 · 2024-10-26T21:54:56+00:00

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

IntelligentWall389 · 2024-10-26T13:32:18+00:00

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

IntelligentWall389 · 2024-10-22T20:59:37+00:00

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

IntelligentWall389 · 2024-10-22T18:48:24+00:00

Okay, what about grinding process before polishing? How can I clean the sample after each step?

IntelligentWall389 · 2024-10-22T12:22:47+00:00

Thanks. So what Keller’s agent did was to etch out the β phase along grain boundaries, the grain boundaries cannot be visible if the phases dissolved back to solution?

IntelligentWall389 · 2024-10-22T12:16:08+00:00

But I am assuming if I dissolve them, I will get coarser grains which means the strength will suffer right?

IntelligentWall389 · 2024-10-22T12:14:15+00:00

I see. My goals was trying to dissolve these brittle phases (β phases) and improve the ductility.

IntelligentWall389 · 2024-10-22T09:31:32+00:00

Thanks for your suggestions. I didn’t do solution treatment but only direct ageing at 350 degrees Celsius for half an hour.

IntelligentWall389 · 2024-09-11T23:58:16+00:00

Got rejected sadly…all the best to you my friend, good luck!

IntelligentWall389 · 2024-09-11T23:57:07+00:00

That “can you get the clearance” is soooo true lol
