Equal channel angular pressing (ECAP), expansion equal (Exp.-ECAP), and hybrid (HECAP) or (Hybrid ECAP) processes were applied to pure copper specimens within this study. After the application of ECAP, die used in Exp.-ECAP process was optimized considering strain inhomogeneity specimen maximum load that occurred during process. Finite element method (FEM), artificial neural network (ANN), gene...

During experimental studies of the equal-channel angular pressing-drawing effect on microstructure evolution and mechanical properties change, principal possibility effectiveness using proposed continuous method for forming an ultrafine-grained structure increasing strength steel-aluminum wire was proved. The deformation carried out at ambient temperature in three passes. It is shown that both ...
