How can a metal change shape and remain crystalline?
After a sufficiently large load is removed, a metal can retain a changed shape.
Sources for this view
Plastic deformation can arise when dislocations move through a crystal. The local atomic arrangement changes as the defect advances; the bulk material need not melt or become a new chemical element.

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.
