RESEARCH AND DEVELOPMENT OF AN SPD TECHNIQUE FOR THE PRODUCTION OF NANOSTRUCTURED ALUMINUM WIRE FOR APPLICATION IN ELECTRICAL ENGINEERING
This paper presents the results of the computer and experimental study of a promising technique of severe plastic deformation (SPD) – Multi-ECAP-Conform (M-ECAP-C) for the fabrication of long-length nanostructured billets (wire rods) with an enhanced strength and electrical conductivity from the aluminum alloy EN-AW 6101 in a single processing cycle. On the basis of the obtained results, a new rational geometry of the pressing channel for the M-ECAP-C technique has been developed. The stress-strained state, structure and mechanical properties of pilot samples of wire rods have been studied. It has been established that processing by the new technique leads produces enhanced mechanical and physical properties.
