COMBINED AND CONSECUTIVE SPD PROCESSING TECHNIQUES
This work presents the analysis of the stress-strained state of billets processed by such SPD processing techniques as "ECAP-Conform", "drawing with shear" and "rotary forging" with a special geometry of anvils. We analyze the influence of processing by these SPD techniques, as well as by their combination with conventional metal working methods, on the structure formation and enhancement of properties in Al and Cu-based alloys, as well as in low-carbon steel. We demonstrate the critical role of the induced non-monotonous deformation in the formation of a combination of enhanced physical and mechanical properties in the investigated metallic materials during treatment by combined and consecutive SPD techniques.
