Cold Working
The plastic deformation of a metal at a temperature below that at which it re-crystallizes. Increasing the amount of cold work causes the dislocation density to rise in the material, making it more difficult to plastically deform the material and eventually cause brittle fracture.
- There are five methods:
- Cold rolling
- Cold drawing
- Cold drawing and grinding
- Turning and polishing
- Turning and grinding
