Circumventing insufficient slip systems: Near-surface dislocation mechanisms allow room-temperature deformation of polycrystalline ceramics

Plastic deformation of polycrystalline ceramics at room temperature is hindered by the lack of sufficient independent slip systems within the material’s structure. Researchers in Germany circumvented this limitation by focusing on deformation in the near-surface region, which demonstrates several useful dislocation mechanisms not available in the bulk region.
