Abstract
The effects of rolling strain during final cold reduction and of post-anneal grain size prior to final reduction on fatigue behavior of the rolled copper foil after recrystallization anneal were examined. The fatigue property was characterized by the bending/unbending fatigue tests. Low rolling strain and large grain size prior to final rolling improved the low-cycle fatigue life due to increase in the ductility of material. High rolling strain and small grain size prior to final rolling improved the high-cycle fatigue presumably due to highly enhanced cube texture.
