Dislocation climb mediated Coble-type grain boundary deformation in gold nanocrystals

Dislocation climb mediated Coble-type grain boundary deformation in gold nanocrystals

Deformation of nanocrystalline materials often involves the grain boundary (GB) dominated creep process. However, the atomistic mechanism of diffusional mass transport along GB remains unclear. Here, we presented a mechanism of stress-driven diffusional climb of GB dislocations in gold (Au) nanocrys...
