Description
Short description:
Dislocations: Investigate FCC/BCC slip systems, stacking faults, and screw dislocation cross-slip in this 40-minute interactive module.
Long description:
This module examines the nature of dislocations in FCC and BCC crystal structures, including Burgers vectors, slip planes, and stacking fault energy. Learners will distinguish between edge and screw dislocations, analyze the formation of stacking faults, and interpret the role of partial dislocations in deformation. The module uses animations and simulations to visualize dislocation motion, equilibrium spacing, and cross-slip behavior—key to understanding work hardening and metal strength mechanisms.
What you will learn
- Differentiate between edge, screw, and partial dislocations and their behavior in FCC and BCC lattices.
- Analyze the effect of stacking fault energy on dislocation mobility and cross-slip phenomena.
