Body-centred cubic (bcc) metals exhibit a distinct plastic response arising from the motion and interaction of dislocations, line defects whose behaviour departs markedly from that in close-packed ...

A Lawrence Livermore National Laboratory scientist and collaborators have demonstrated the first-ever "defect microscope" that can track how populations of defects deep inside macroscopic materials ...

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, ...
