Layers of rust
I ran across this scene a few days ago and thought it was interesting in several aspects. Some of those were visual, some of them not.
As the title says, this is layers of rust. I'll share the "not" aspects after somebody guesses what the rusted thing was.
Stereo pairs follow, crossed-eye.
Nikon D800E, Mitutoyo M Plan Apo 5X with Raynox 150 tube lens, extension slightly increased for better framing. Zerene Stacker PMax, synthetic stereo.

Edit: corrected typo, "Raynox 105" --> "Raynox 150".

Surfaces always tend to rust in flakes, because it forms in a layer then comes off because there's a volume increase, which raises stresses.
First I read "Raynox 105" as 105mm so quite thick flakes, but Raynox 150 would be 210mm so not so thick.
Thick rust, with quite thick flakes, makes me think the layering might be related to an internal structure of the original material. Like a forged leaf spring.
I've never studied rust though, it's not good for much!
I'll go for a forging or rolled piece rather than a straight casting. The layers are sometimes called "mechanical fibering". Cast thin sections can show it too though.
I dare say it would be possible to tell the difference between something rusted in a marine (salty) environment versus dry air, or underground, etc. One for Abby Sciuto.

These pairs are intended for cross-eyed viewing. You must be managing to fuse them parallel. If you want to do that, then pull them into StereoPhoto Maker and press the Swap Left/Right button.pontop wrote:To my eyes it looks like it is floating behind everything else.
Magnet, no.
Focus block, no.
Leaf spring, no.
Forged or rolled, probably.

Not railroad track, and not a file.
Not an antiquity, either. It is modern manufacture.
An odd fact that may also be a hint: this was a key supporting component in a piece of equipment that was fully functional and used several times daily until 3 days ago, when I replaced it for fear of imminent and catastrophic failure.
