Climb is the motion of an edge dislocation normal to its slip plane. The process requires the addition or removal of atoms from the extra half plane of the dislocation by diffusion processes. Climb is ...

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 ...

Lattice defects generated by radiation damage can diffuse to grain boundaries (GBs) and be annihilated at GBs. However, the precise role of GBs in annihilating the segregated defects remains unclear.

Dislocation creep is a deformation mechanism transporting shear through the crystal lattice by the motion of line defects, called dislocations. This mechanism involves the elementary processes of ...

Plastic fantastic? Quasicrystal deformations and bending observed. When shrunk to the nanoscale, quasicrystals become plastic. That is the finding of an international team of researchers, which says ...
