Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. These linear defects, or dislocations, are what ...

Dislocation dynamics examines the behaviour of line defects within crystalline materials—imperfections that are central to understanding plastic deformation. At the microstructural level, the motion ...

(Nanowerk News) Settling a half century of debate, researchers have discovered that tiny linear defects can propagate through a material faster than sound waves do. Dislocations in materials can ...

Researchers have used artificial intelligence to solve a difficult problem in crystal science. Seeking to understand why crystals develop tiny defects called dislocations, the researchers discovered ...

Imperfections of crystal structure, especially edge dislocations of an elongated nature, deeply modify basic properties of the entire material and, in consequence, drastically limit its applications.

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 ...

Scientists at Nagoya University in Japan harnessed the power of artificial intelligence to unveil a novel approach to comprehend small defects known as dislocations in polycrystalline materials.

Crystals are known far and wide for their beauty and elegance. But even though they may appear perfect on the outside, their microstructure can be quite complicated, making them difficult to model ...
