How Dislocations Make Metals Deform

A raft of bubbles provides a visual model of atoms arranged in a hexagonal lattice. I use it to explain how dislocations move under stress and how temperature affects the deformation of metals.

- Bubble lattices and edge dislocations
- Dislocation movement, atomic-plane shear, and changes in material shape
- How higher temperatures make dislocation motion easier and metals softer

For viewers learning about materials science, this demonstration connects lattice defects to metal deformation. Watch for how the bubble model illustrates the role of stress and temperature; the discussion focuses on dislocations rather than a broader survey of metal properties.
