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.

Famous quotes containing the words dislocation and/or creep:
“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.”
—Ralph Waldo Emerson (1803–1882)
“Winter lies too long in country towns; hangs on until it is stale and shabby, old and sullen. On the farm the weather was the great fact, and men’s affairs went on underneath it, as the streams creep under the ice. But in Black Hawk the scene of human life was spread out shrunken and pinched, frozen down to the bare stalk.”
—Willa Cather (1873–1947)
