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 ...

Researchers have combined numerical modeling of dislocation glide and results from diffusion experiments to revisit the rheology of wadsleyite, ringwoodite and majorite garnet under geological strain ...

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 ...

Despite being composed of solid rocks, the Earth's mantle, which extends to a depth of ~2890 km below the crust, undergoes convective flow by removing heat from the Earth's interior. This process ...
