 abstract={The study of the mechanical properties comprised fracture surface examination, texture and microstructure observations of copper samples, which were cold rolled, beginning from the recrystallized state or initially deformed by Equal-Channel Angular Pressing (ECAP) up to equivalent deformation E= 2.7. In cold rolled recrystallized copper, intensive shear band formation on the sample scale as well as on micro-scale was observed; shear bands in cold rolled copper, initially ECAP processed, were difficult to observe. Higher ultimate strength and greater elongation were measured in tensiled samples, cut out in RD direction of rolled to z= 96% copper sheet and preliminarily ECAP processed samples; strain marks on the lateral surface of such a sample in the neck region demonstrated the grain size diameter lower than I μm. Fracture surface observation of ruptured sheet samples of recrystallized copper has shown that it is possible to explain the lower elongation as a result of localised deformation in shear bands. In both cold rolled sheets, texture with \{ 112 \}<11-1> ideal orientation was observed, although in preliminarily ECAP processed copper the dispersion of crystal orientation around the ideal orientation was smaller.},
