Why are metals so stretchy? (2^13 sub special)

Күн бұрын

It's play button time, and today it's made from copper foil - a surprisingly stretchable material. You wouldn't think that crystalline materials like metals could deform without destroying the atomic pattern that gives them their strength and electronic properties, but with the help of a crystal defect called a dislocation, it's super easy. Dislocations are agents of plastic deformation, traveling through crystals and enabling malleability and ductility in soft metals like copper, making them great raw materials! I hope you enjoy this dive into the materials science of plastic strain, and if this is your first video here, be sure to subscribe for more!
Thanks to all my OG subscribers, and welcome to the new ones! And a big thanks to Steve Mould for sending some of his awesome fans my way. / steventhebrave
Corrections and Clarifications:
- "Plastic deformation" is a term that means a permanent change in shape, even in metals, we call it plastic.
- There are also grain boundary considerations in polycrystalline materials that I don't address at all - mostly it shows up in tension, because bubble rafts aren't ACTUALLY very ductile.
- More to add when I get convinced I'm wrong!

@@AlphaPhoenixChannel It was in mine! Actually it was before my Materials 101, it was in Engineering 102, which every engineering student goes through before specialising further. I love the demo, it's so versatile and a surprisingly accurate analogue! We used different sized bubbles to simulate interstitial and substitutional impurities (kind of, interstitial doesn't work as much in 2d). We outlined grain boundaries, and observed dislocations not passing grain boundaries. All in all, a fun lab class. Steve Mould has a video doing a similar thing with ball bearings getting vibrated and simulating the annealing process.

i've seen this demonstration with little metal beads, but never with bubbles. it's pretty amazing how you set it up to make all the bubbles the same size

@AlphaPhoenixChannel 3 жыл бұрын

Yeah the metal beads are awesome for showing how repulsion between atoms causes spontaneous ordering (crystallization) but they aren't sticky enough to easily get motion behavior like dislocations gliding effortlessly through. I wasn't lying when I said my jaw hit the floor when I first saw Bragg's lecture video using bubbles. It's so ludicrously cool. Also don't look too close at some of the shots if you think all of my bubbles were successfully the exact same size lol.......... It's actually pretty fun to see what crystal defects you get when you do have different sizes - you can get weird sized bubbles stuck to dislocations (or dislocations stuck to weird sized bubbles) because they relieve some of the strain associated with having an extra half-plane of atoms wedged in the crystal.

What I am loving in particular about the bubble demo versus the the steel ball demo, is that the bubbles have some give (like atomic bonds) so I feel that the resulting effect is more analogous to a crystal structure.
