In situ transmission electron microscopy straining experiments with concurrent macroscopic stress–strain measurements were performed to study the effect of microstructural heterogeneity on the deformation behavior of nanocrystalline metal films. In microstructurally heterogeneous gold films (mean grain size d m =70nm) comprising randomly oriented grains, dislocation activity is confined to...
A survey of the yield strength and hardness of copper-based materials shows a progressive lowering of the strength with respect to the extrapolation of the Hall-Petch relation as the length scale of the microstructure decreases. The overall trend can be modeled by scaling the elastic screening length for the dislocation line tension with the microstructural length scale, as proposed by Scattergood...
