Which observations separate shape recovery from a permanent bend?
For matched metal specimens, record the initial dimensions and processing history, apply a controlled load, and measure the unloaded shape. Additional force and displacement records would show where recoverable and permanent responses differ.

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.
