The 31 pages that link to Dislocation, each with the reason it gives.
MetallurgyRelated: Dislocation motion underlies the strength and ductility of many metals.
HardnessRelated: Dislocations govern much of the plastic flow resisted during indentation.
FatigueRelated: Repeated movement of dislocations contributes to microscopic fatigue damage.
MisorientationRelated: Low-angle misorientations can be accommodated by arrays of dislocations.
