摘要：

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-mu m-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 in plasticity. Changes in strain-rate sensitivity and activation volume for deformation upon cycling were measured and utilized to discuss possible mechanisms responsible for the observed strengthening.
