Optimizing the ECAP processing parameters of pure Cu through experimental, finite element, and response surface approaches

Abstract The main aim of the current work is to investigate effect equal channel angular pressing (ECAP) processing parameters, namely, number passes, ECAP die angle, route type, and temperature on mechanical electrical properties pure copper (Cu). finite element method was used simulate homogeneity stress plastic strain distribution during processing. response surface methodology (RSM) identify optimum parameters by analyzing impact conditions responses. A second-order regression model analysis variance were created analyze condition genetic algorithm (GA) also applied optimize condition. Finally, a hybrid RSM–GA improve optimization responses corresponding evaluated using GA. developed models validated compared with experimental findings prove that they are reliable as predictive tools. revealed Bc more effective in improving hardness, yield stress, ductility, energy whereas ultimate tensile strength conductivity Cu billets. Furthermore, for identified individually.
