The Hall–Petch and inverse Hall–Petch relations and the hardness of nanocrystalline metals (2019, background): “Although MD simulations allow researchers to directly model atoms and investigate grain boundary structure for grains less than 10 nm in size [86], the simulated strain rates are so high as to be inaccessible experimentally [87] (see the discussion of Fig.”
Review of Nanoindentation Size Effect: Experiments and Atomistic Simulation (2017, methodology): “In the case of crystalline metals, many different aspects of nanoindentation experiment, such as initial dislocation nucleation and evolution pattern [79,81,83], the effect of surface step [80], effects of GB [84,88,126,127], the effect of film thickness [128], the effect of substrate [129], the eff”
The role of heterogeneous deformation on damage nucleation at grain boundaries in single phase metals (2009, background): “Additionally, boundaries impose a threshold stress effect, such that strain bursts through a boundary occur with increasing stress/strain due to achieving a stress sufficient to activate a grain boundary source (Wang and Ngan, 2004; Hasnaoui et al., 2004; Kobayashi et al., 2005)).”
