The purpose of this study is to investigate the effects of a nano − scale stress − field on fatigue damage in a nano − copper component under fu] ly − reversed loading. A resonant fatigue experiment is carried out for a cantilever micro − specimen that has a polycrystalline nano −Cu sandwiched by Si, Ti and SiN. Crystallographic slip bands associated With extrusion / intrusion of about 30 nm width , which is much finer than that in the bulk copper ( 1 pm ) , are fermed on the Cu surface .
