In materials science, a dislocation is a linear crystallographic defect or irregularity within a crystal structure that contains an abrupt change in the arrangement of atoms. The movement of …

Crystal dislocation is defined as a defect within a crystal structure that allows for plastic deformation under applied shear stress. It is characterized by a misalignment of atoms, which …

Dislocation movement related to lattice resistance strongly depends on the activation energy for their lattice barrier and the activation distance.

In materials science, a dislocation is a crystallographic defect or irregularity, within a crystal structure. The presence of dislocations strongly influences many of the properties of materials.

The advent of advanced techniques of atomic-scale probing have facilitated modern observations of dislocations in every crystal structure-type, particularly by x-ray diffraction topography and …

It is believed that dislocations originate mainly when a crystal is stressed, but some may be produced during the solidification of the metal, due to impurity atoms and thermal vibrations.
