The analysis of the impact of the new combined process “equal channel angular pressing - drawing” on the microstructure and properties of deformed copper wire

The problem of resource-saving methods of producing materials with properties combining high strength and ductility in conditions of using relatively simple and inexpensive devices that enable to implement the whole bulk of metal and intensive plastic deformation while using the minimal amount of energy and effort is very important. In manufacturing wire from non-ferrous metals and alloys, this problem can be solved by using a combined method of deformation “pressing-drawing“ which has a significant advantage compared with the existing technology of producing copper wire. This method of deformation enables to produce wire with a sub-ultrafine grained structure and a high level of mechanical properties, required dimensions and a cross-sectional shape with a small number of deformation cycles.
