Abstract
In order to investigate the fatigue behavior of submicron gold single crystal, a resonant fatigue experiment is conducted. Crystallographic slip bands appear on the specimen surface due to fatigue. The critical value for slip band formation is evaluated to be over 200 MPa, which is over six times larger than that of persistent slip bands (PSBs) in the bulk counterpart. Cross-sectional electron microscopy observations reveal that extrusions/intrusions that are about 60 nm wide form on the surface at slip bands. Although the slip bands have similar morphologies to those of PSBs, they are much narrower.
