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 ...

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, ...

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 ...

AMES, Iowa – Materials engineers don’t like to see line defects in functional materials. The structural flaws along a one-dimensional line of atoms generally degrades performance of electrical ...

Illustration of an intense laser pulse hitting a diamond crystal from top right, driving elastic and plastic waves (curved lines) through the material. The laser pulse creates linear defects, known as ...
