Deformation
Force application.
Distortion occurs (material still elastic state)
Force removal - original shape maintained.

Slide 5 - Slide

This item has no instructions

Deformation Cont'
Force application.
Distortion occurs (material pushed past yield point)
Force removal - deformed shape.

**Slip has occurred in atomic lattice along the slip bands**

Slide 6 - Slide

  • Slip planes are used up until none remain and fracture will occur - Before this, the metal is work-hardened.
  • Metal is strong and hard in this condition but has lost its ductility. Recovery in the form of annealing
What are the three key elements in metal deformation?
