Dislocation dynamics form the cornerstone of our understanding of plastic deformation in crystalline metals and alloys. These line defects traverse crystallographic planes under applied stress, giving ...
Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...
Minerals form the building blocks of almost everything on Earth. They are made up of crystals - regular, repeating atomic structures that fit together like a three-dimensional pattern. When minerals ...
Jogs and kinks are atomic scale changes in direction of a dislocation line. Jogs are out of the slip plane and kinks lie in the dislocations slip plane. For the edge dislocation shown, the jogs are of ...
The energy of a dislocation depends on its position in its slip plane. The diagram represents a slip plane with a position dependent potential having a period, a, determined by the location of rows of ...
