Ultra-fine grain (UFG) Cu-Cr alloy is prepared by equal-channel angular pressing (ECAP). The microstructure, tensile and fatigue properties of the UFG Cu-Cr alloy were investigated. The bulk materials with average grain size of ∼230 nm were obtained through ECAP for 12 times. The cellular subgrains
