dc.description.abstractThe effect of inclusion of a grain boundary in nanopillar was studied using Al bicrystal with [3 43]/[13 (17) over bar 14] orientation. Ex situ compression results showed higher strengths in bicrystal pillars than in single crystal pillars, which is explained with respect to the reduced single-armed source length that was confirmed in the in situ TEM tests. Molecular dynamics simulations indicated that the grain boundary can assist in dislocation nucleations without resulting in dislocation pile-up at the boundary.-
