Severe plastic deformation (SPD) has gained attention to ultrafine grained (<500 nm) and nano-grained (<100 nm) bulk materials producing. Equal channel angular pressing (ECAP) is the most common SPD process. ECAP has three critical disadvantages such as industrially discontinuity, limited small products, and non-uniform deformation such as gross distortions at the front and back of every billet. In this study, we systematically studied on an alternative approach which ECAP combined with the Conform process, developed for continuous extrusion-forming of metal wires (ECAPConform).The as-casted dilute copper alloys have been subjected to ECAP-Conform. The microstructural evaluation and hardness distribution have been investigated before and after ECAP-Conform.
