Abstract: The aim of this work was to study the microstructure and mechanical properties of copper, brass CuZn36 and bronze CuSn6 strips annealed and after repetitive corrugation and straightening (RCS) process. The influence of process parameters on the functional properties of strips was investigated. The study found an increase in the yield strength and tensile strength of the material after RCS process. Crystallite size measurement confirmed the presence of nanoscale structures in the studied materials after deformation by RCS process. The used method of plastic deformation is promising for development materials with improved functional properties. The paper presents also the results of numerical simulations of Cu strip after corrugation on groove and tooth rolls and next straightening. Rolling process simulations were conducted using Forge 2011® based on the finite element method.
