Copper, due to its properties of typical materials used in the electrical industry (e.g. susceptibility to
metal working, corrosion resistance, high thermal conductivity, high electrical conductivity and the
ability to create numerous alloys with significant technical sense), is regarded as one of the most
popular wire materials. More than half of the produced copper is used up in production of wires and
cables in the electrical industry.
Achieving very high mechanical and electrical properties in the products made of copper alloys is not
easy and requires the use of appropriate alloying elements and use of appropriate metal working and
heat treatment. Numerous studies have shown that achieving the high strength and the high electrical
properties for Cu-Ag alloys is possible when we reach nanometric microstructure. Achieving such
microstructure is possible by applying the methods of severe plastic deformation (SPD). The SPD
techniques used for the refinement of the structure are: ECAP, CWS, HPT, KOBO, RCS, ARB and
others. In addition to the techniques mentioned above also applying of a combination of conventional
forming processes with suitable sequence of deformation can contribute to substantial refinement of
the material structure.
In this work it was decided to prepare CuAg15 alloy wires and perform processing technology of
severe plastic deformation – repetitive corrugation and straightening (RCS). Thus obtained material
was subjected to the investigation of mechanical properties and microstructure.
