Influence of the forming tool parameters on the grain refinement of brass by SPD process

Original language description

Development of technologies for the production of very fine-grained materials is currently very intensively accelerated. On VSB -Technical University of Ostrava developed a method that uses the principle of severe plastic deformation to refine the structure and enhance mechanical properties of sheet metal strips. The greatest importance in practice represents an increase in proof stress and tensile stress of sheet metal strips. Dual Rolls Equal Channel Extrusion (DRECE) method is a newly developed method. Severe plastic deformation results in a high degree of the material reformation. The method can be used to produce metallic materials with a very fine grain structure (hereinafter referred to as ultrafine grain structure). The forming process is based on extrusion technology with zero removal of the sheet strip thickness with the ultimate aim of achieving a high degree of deformation in the formed material, resulting in a significant improvement of mechanical properties in the input material. The paper analyses the effects of the values of angles of the newly developed forming tools on the achievement of mechanical properties in selected materials Cu and brass in the SPD process. The following types materials were verified experimentally - strip sheet with dimensions 58 (width) x 2 (thickness) x 1000 (length) mm. The paper also evaluates the influence of severe plastic deformation (SPD) on strengthening these materials at different values of the angle in the forming tool. The influence of new geometries of forming tools for improving mechanical properties has been unequivocally demonstrated.
