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 ...

An anterior shoulder dislocation occurs when the shoulder slides forward out of the socket. It is usually the result of a sports injury, fall, or traffic accident. This shoulder injury is the most ...

For nearly a century, scientists have understood how crystalline materials—such as metals and semiconductors—bend without breaking. Their secret lies in tiny, line-like defects called dislocations, ...

Creep is the time‐dependent, permanent deformation of metals subjected to constant load at elevated temperature. It proceeds through three characteristic stages: primary creep with a decreasing strain ...
