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 ...

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 ...
