摘要: Abstract Nanolayered materials exhibit unique plastic deformation behavior, i.e. , a bulk-like to small-scale plasticity transition and scaling behavior of extremely small activation volume ( V * b 3 ) with intrinsic size. This unusual phenomenon likely stems from the dislocations respectively emit interfaces Frank–Read-type bulk sources below above critical size ∼20 nm. We quantitatively capture relationship between strain rate sensitivity by phenomenological model based on Orowan–Frank–Read process.
