Development of production technology of very fine-grained material is currently very intensively accelerated. Even in scientific research, it is recognized that precisely controlled forming processes, including special processes, enabling control of technological parameters with regard to the structure and its further refinement, currently has the highest gradient utilization efficiency of scientific research findings into practice. Besides the methods C2S2 and ARB for sheet metal forming, in terms of industrial practice intensively develop new technologies, to which also belongs Dual Rolling Equal Channel Extrusion (DRECE) method. Forming device that uses the method in question is currently being installed at the workplace in Centre of Advanced Innovation Technologies, VSB Technical university of Ostrava. Experimentally were verified steel DC 01- strip sheet with dimensions 58 (width) x 2 (thickness) x 2 000 (length) mm. The paper evaluated the influence of severe plastic deformation (SPD) on the quality this steel at sizes angle forming tool 108°. In the present work are solved structural characteristics of carbon steel DC01 after application DRECE method, including an assessment of basic mechanical properties, that are important for application scientific research findings into practice.Keywords: Severe plastic deformation, DRECE method, forming tool, steel DC01, structure and mechanical properties
