Do different colors mean different elements?
Electron backscatter diffraction scans positions with an electron beam and uses diffraction patterns to infer crystal orientation. In the cited NIST examples, map colors encode orientation and crystalline structure, not a paint-like chemical composition map.

EXPLORE THE MODEL
Slip changes the arrangement
Inspect the structure; select a site or component for its label.
What this representation means
A simple array illustrates relative slip across a plane. It is not an iron crystal structure, a computed dislocation core, a stress calculation or a measured micrograph.
- Inventory
- 80 markers before and after slip
- Structural scope
- Simple lattice schematic, not a named metal crystal
The upper part moves relative to the lower part while all markers remain. Real plastic deformation often proceeds by dislocation motion; this simplified slip sequence does not resolve a dislocation core or specify the force needed.
What this model can establish
A simple array illustrates relative slip across a plane. It is not an iron crystal structure, a computed dislocation core, a stress calculation or a measured micrograph.

HISTORY THROUGH EVIDENCE
Evidence before the atomic picture
Crystalline diffraction and permanent deformation had to be explained together.
