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 …

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

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 …

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 …

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.

Jan 6, 2016 · The advent of advanced techniques of atomic-scale probing has facilitated modern observations of dislocations in every crystal structure-type, particularly by X-ray diffraction …

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.

Jan 1, 2024 · The dislocation line is the boundary line between the area that experiences relative displacement on both sides of a geometric surface in the crystal and the other areas that do …

A dislocation is a linear or one dimensional line defect which involves translation of one part of a crystal with respect to another part. A disclination involves rotation of one part with respect to …

This Special Issue on “Crystal Dislocations: Their Impact on Physical Properties of Crystals” covers a broad range of physical properties involving dislocations and their impact on crystal …

Jun 1, 2025 · Abstract: This work introduces a quantitative model for the Frank-Read source, considered to be one of the most important micro-mechanical mechanisms of dislocation …

A dislocation is a type of crystal defect characterized by an irregularity within the crystal lattice structure. This defect occurs when there is a misalignment of the atomic planes, which can …

In this lecture, I shall talk mainly about the mechanical effects of dislocations in crystals.

The most important role is to weaken the crystal strength. The role of dislocations in materials involves the interactions of a dislocation with other dislocations and defects in the material, …

Dislocations in crystals are defined as line defects that play a crucial role in the plastic flow of crystalline materials, acting as sources of long-ranged elastic stresses and strains.

In material science, dislocations are lattice defects within a crystal structure. Dislocations occur when stress is applied and can move from atom to atom, causing plastic deformation.

The Special Issue on “Crystal Dislocations” is intended to provide a unique international forum aimed at covering a broad range of results involving dislocations and their importance on …

Crystal dislocations can be defined as linear defects within a crystal structure characterized by misalignments of atoms, which can arise from slip processes or crystal growth, and are …

The Special Issue on Crystal Dislocations is intended to provide a unique international forum aimed at covering a broad range of results involving dislocations and their importance in …

Crystal dislocations are linear defects in crystalline structures that arise due to irregularities in the periodic arrangement of atoms, affecting the material's mechanical properties.

2 days ago · Moreover, the dislocation density on the C-face was significantly higher than that on the Si-face, and the stress released by dislocation slip led to better surface quality on the C …
