Purpose: A growing trend to use the new copper-based functional materials is observed recently world-wide. Ultrafine grained copper, solid solution hardened and age-hardened copper alloys are applied where combination of high electrical conductivity with high strength is required. Design/methodology/approach: This study was aimed to investigate microstructure in strips of copper alloys with different stacking fault energy value. The investigated materials have been processed by one of the severe plastic deformation method, using different variants of continuous repetitive corrugation and straightening (CRCS). Deformation was executed by parallel and perpendicular corrugation and straightening of strip sample. Findings: Continuous repetitive corrugation and straightening is a promising method for refining of microstructure of metallic strips. Practical implications: A growing trend to use new copper-based functional materials is observed recently world-wide. Within this group of materials particular attention is drawn to those with ultra fine or nanometric grain size. Originality/value: The paper contributes to the microstructure evolution of solid solution hardened and age-hardened copper alloys strips produced by original RCS method.
