Weird Weird Science posted this extreme zooming video on the structure of steel – quite awesome. They have video for concrete, brass, aluminium and more available as well. – Weird Weird Science on Dailymotion

Should you prefer a little more color & motion, check out Trey’s macro video of a plasma ball in action –

10 thoughts on “Zoom into steel (to the atomic level!)

  1. The “cavity” they travel into in the video is NOT a defect or erosion, it’s there because this is a powder casted part.

    Powder casting is the most common way to make gears these days. Voids like this are a normal feature of powder casting because you fill the mold with powder, compress and heat it which causes *partial* melting and fusing, and you’re done. It’s very cheap and the finish looks no different superficially than a machined gear (the other method). The technique is also common for casting ceramics.

  2. This video about steel is so full of inaccuracies that I don’t even know when to start correcting! If they can get metallurgists to provide those images, they should get proper explanations and terminologies. Carbon to protect from corrosion? Dendrites on a fractograph? Sheesh.

  3. The one that made my teeth hurt was their explanation of tempering.

    That was so “I saw this video where a guy took a samurai sword and cut through a piece of train track” bad that I had to check something and, sure enough: In “The Making, Shaping and Treating of Steel, 10th Edition” they claim to be showing the microstructure of pearlite at 1000x, not 10,000-50,000x. I don’t know what we were looking at in that video, but I’m gonna bet on the Association of Iron and Steel Engineers on this one.

  4. Forgive my ignorance, but can one really zoom into the atomic level with a microscope?

    With all the other errors in this video, I was wondering if this was a gross misstatement by the narrator…

    Comments rule. Thanks!

  5. @Volkemon – I was assuming the video was actually composited from multiple shots – and yes, these comments do rule. Thanks for the insight, everybody!
