Modeling of the plastic deformation of nanostructured materials with grain size gradient (2012, background): “grain-boundary sliding (Schiotz and Jacobsen, 2003) and grain-boundary diffusion (Keblinski et al., 1998; Yamakov et al., 2002)) played an increasingly important role as compared with that of intragrain dislocation mediated plasticity with decreasing grain size in nano/ultrafine grained materials.”
Deformation-mechanism map for nanocrystalline metals by molecular-dynamics simulation (2004, background): “However, an important difference between the two materials arises from the strong, d −3 – d −2 grain-size dependence of the competing GB-based deformation process (namely GB-diffusion creep”
