The influence of cyclic load, with the maximum stress well within the elastic regime, on the strength of nanocrystalline (nc) nickel was investigated through quasi-static compression experiments on cyclic-loaded sub-μm-sized pillars, fabricated through electron beam lithography and electroplating. Results show that prior-cycling enhances both yield and flow strengths of nc Ni without significant loss...
The effects of specimen size and strain rate on the plastic deformation response of sub-μm-sized nanocrystalline Cu pillars were examined through a series of micro-compression experiments, with particular emphasis on the stochastic nature of the measured responses. A large number of micropillars two different diameters, both with an average grain size of 6 nm, were prepared by employing the single...
