We propose a novel dual-mode CLS model aimed at enhancing the accuracy of stress predictions across a wide range of layer thicknesses and various slip angles. Our findings indicate that with decreasing layer thickness and the loss of lattice structure, the FCC/HCP interface becomes unstable and ...
For layer thicknesses in the range of a few to tens of nanometers, the strength of these materials is related to the stress required for individual dislocations to thread through the nanometer-thick layers, a motion called confined layer slip (CLS). Here, using atomistic...
Confined layer slip (CLS) is considered as the primary mechanism for plastic deformation in nanolaminates. It depicts the confined motion of a single dislocation between two parallel interfaces nanometers apart. Using atomistic simulations, we investigate the effects of interface spacing, or equivalently...
To account explicitly for the effects of layer thickness and biphase interface on crystallographic slip, the model features a hardening law, called dual-mode confined layer slip (CLS). The model is applied to a suite of stress-strain measurements made on Mg/Nb nanocomposites, varying layer ...
In this study, we model confined layer slip in three structures: nanolaminated Ag and two types of Ag/Cu nanolaminates. We find that the glide motion is jerky in the presence of incoherent interfaces characterized by distinct arrays of misfit dislocations. In addition, the glide planes exhibit ...
