New Combined Process “Pressing-drawing” and Impact on Properties of Deformable Aluminum Wire

Abstract The aim of this work is to study the influence of the combined process of “pressing-drawing” on the microstructure and mechanical properties of aluminum wire. Analysis of the results of the research has shown that the proposed combined method of deformation “pressing-drawing” has a significant advantage over the existing technology of production of aluminum wire. This method of deformation due to combination of two ways: by severe plastic deformation in equal channel step die and the process of drawing through a drawing die, allows obtaining aluminum wire with ultrafine-grained structure and a high level of mechanical properties, required size and shape of the cross section at a small number of cycles of deformation. Also would like to mention that this method of deformation in implementing it in production does not require significant economic investments, and substantial refitting of existing drawing mills.
