Inconel 625 etching
Inconel 625 etching
(OP)
Hi,
Could anybody help with a suitable etchant for revealing grain strucutre for grain size determination in Inconel 625, I'm guessing mixed acids is the way to go? I am aware a bit trial and error would be the best solution but as I am waiting for the components I thought I would ask the question.
Thanks

2. you can have little to no precipitates, it depends on anneal temp, cooling rate, and cold work
Can you see the acicular phase without etch (polarized or DIC)?
What is the product for and what is its thermo-mechanical history?

Looks more like deformation than structure.
