Microstructure versus size: mechanical properties of electroplated single crystalline Cu nanopillars.
We report results of uniaxial compression experiments on single-crystalline Cu nanopillars with nonzero initial dislocation densities produced without focused ion beam (FIB). Remarkably, we find the same power-law size-driven strengthening as FIB-fabricated face-centered cubic micropillars. TEM analysis reveals that initial dislocation density in our FIB-less pillars and those produced by FIB a...
متن کاملThe In-situ Mechanical Testing of Nanoscale Single-crystalline Nanopillars
Common materials like metals appear to have unique and interesting properties when reduced to nanoscale. One example is that they become signifi cantly stronger, exhibiting strengths an order of magnitude higher than bulk. Understanding material strength at the appropriate scale is crucial in the design and reliable functioning of devices comprised of these materials. This article reviews recen...
متن کاملSize effects in Al nanopillars: Single crystalline vs. bicrystalline
The mechanical behavior of bicrystalline aluminum nano-pillars under uniaxial compression reveals size effects, a stochastic stress– strain signature, and strain hardening. Pillar diameters range from 400 nm to 2 lm and contain a single, non-sigma high angle grain boundary oriented parallel to the pillar axes. Our results indicate that these bicrystalline pillars are characterized by intermitte...
متن کاملAtomistic characterization of pseudoelasticity and shape memory in NiTi nanopillars
Molecular dynamics simulations are performed to study the atomistic mechanisms governing the pseudoelasticity and shape memory in nickel–titanium (NiTi) nanostructures. For a h110i – oriented nanopillar subjected to compressive loading–unloading, we observe either a pseudoelastic or shape memory response, depending on the applied strain and temperature that control the reversibility of phase tr...
متن کاملCrystalline cellulose elastic modulus predicted by atomistic models of uniform deformation and nanoscale indentation
The elastic modulus of cellulose Ib in the axial and transverse directions was obtained from atomistic simulations using both the standard uniform deformation approach and a complementary approach based on nanoscale indentation. This allowed comparisons between the methods and closer connectivity to experimental measurement techniques. A reactive force field was used that explicitly describes h...
