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 ...

Shoulder dislocations usually occur without warning, but you are most at risk when your arms are spanning. Miho Nonaka crushes holds on her way to gold at the 2018 World Cup in Switzerland. A year ago ...

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 ...

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 ...
