Crystal defects {dislocation, crystal} can displace unit cells from usual positions. Inserted atoms wedged into lattice can cause dislocations {edge dislocation}. Dislocations {screw dislocation} can be around axis to make helical unit-cell arrangements. Dislocations in crystals affect brittleness, ductility, and other mechanical crystal properties. Alloys lack dislocations and so do not slide, because odd atoms move to lowest free-energy positions.
