Dislocation creep

Schematic representation of an edge dislocation in a crystal lattice. The yellow plane is the glide plane, the vector u represents the dislocation, b is the Burgers vector. When the dislocation moves from left to right through the crystal, the lower half of the crystal has moved one Burgers vector length to the left, relative to the upper half.

Schematic representation of a screw dislocation in a crystal lattice. The yellow plane (Σ) is again the glide plane, u the dislocation and b the Burgers vector. When the dislocation moves from the back to the front of the crystal, the lower half moves one Burgers vector length to the front, relative to the upper half.

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.
