摘要：

Equal channel angular rolling (ECAR) is a severe plastic deformation method that covered plastic deformation of sheets. In this study, the mechanical properties of bimetal sheet (Al/Cu) that joined by explosive welding method has been investigated. The specimens were annealed and severely plastically deformed by 8-pass equal channel angular rolling process at the route A. The results demonstrated that yield and tensile strengths significantly increased after the first pass. Also elongation decreased by this process. SEM images showed that a shear deformation that influenced on grain boundaries angle and grain size. By increasing the number of ECAR passes grain boundaries angle increased and grain size decreased.
