Method DRECE (Dual Rolls Equal Channel Extrusion) belongs to a perspective group of technologies utilizing the process of severe plastic deformations (SPD). Used for forming of metallic materials. On the newly developed forming device, unlike the rolling technology, the material is significantly strengthening after the forming process, while maintaining the initial strip sheet dimensions after the first pass through forming device. We want to achieve a significant increase in mechanical properties in as few passages as possible by the forming device, in particular increasing the yield strength Rp0.2 and the ultimate tensile strength Rm, while maintaining good formability. The above-described forming method was used to extrude of two types low carbon steel HC200AM and S235JR. The forming tool, according to the pre-performed experiments, was chosen with an inclination of 108° in the deformation zone. The mechanical properties obtained after first pass through the forming device from the tensile tests.
