Dislocation creep is a deformation mechanism in crystalline materials. Dislocation creep involves the movement of dislocations through the crystal lattice of the material. It causes plastic deformation of the individual crystals and in the end the material itself.
Dislocation creep is highly sensitive to the differential stress on the material. At relatively low temperatures it is the dominant deformation mechanism in most crystalline materials.

“For, as it is dislocation and detachment from the life of God, that makes things ugly, the poet, who re-attaches things to nature and the Whole,—re-attaching even artificial things, and violations of nature, to nature, by a deeper insight,—disposes very easily of the most disagreeable facts.”

If not in a place, where are the People weeping?
