Abstract

It is shown that the twist hydroextrusion results in the formation of fine crystalline structure with grains of elliptical shape oriented at an angle of ≈450 to the axis of deformation. Mechanical properties of the processed copper are characterized by a high level of strength and plasticity characteristics. Peculiarities of the formed structure are inherited under the subsequent rolling, they are in untypical location of grains relative to the axis of deformation.
