Question: 1. In the FCC structure, a perfect dislocation having b=1/2 resolves into two glissile partial dislocations. Show how the perfect dislocation resolves in (111) plane.

1. In the FCC structure, a perfect dislocation having b=1/2 resolves into two glissile partial dislocations. Show how the perfect dislocation resolves in (111) plane. Explain the reason why the partial dislocation is more stable than the perfect dislocation. Also, explain the reason why the ribbon of stacking-fault is formed after the dissociation of a perfect dislocation
