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 ...

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 ...

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 diagram shows the location of atoms close to an edge dislocation line that runs back into the screen. The green circle outlines a group of atoms close to the dislocation line that have larger ...
