Downscaling the ECAP process — •Aikaterini Zi, Ralph J. Hellmig, and Yuri Estrin — Institut für Werkstoffkunde und Werkstofftechnik, Technische Universität Clausthal, Agricolastr. 6, 38678 Clausthal–Zellerfeld

Equal Channel Angular Pressing (ECAP) is a well–known severe plastic deformation method used to produce ultra–fine grained materials. The dimensions of ECAP specimens are usually in the centimetre range. Downscaling the ECAP process may be a viable option for producing high strength wires or fibres in the millimetre range. A multi channel die with channel diameter of 2 mm was used for that purpose. Microstructure investigations demonstrating significant grain refinement confirm the viability of this approach.
