Atomic-Level Observation of Disclination Dipoles in Mechanically Milled, Nanocrystalline Fe

Plastic deformation of materials occurs by the motion of defects known as dislocations and disclinations. High-resolution transmission electron microscopy was used to directly reveal the individual dislocations that constitute partial disclination dipoles in nanocrystalline, body-centered cubic iron...
