dcterms:description
Increase of mechanical properties in sheets, obtained by severe plastic deformation is very important for final manufacture of machine parts produced from such blanks. At the VŠB - Technical University of Ostrava, Faculty of Mechanical Engineering special equipment DRECE (Dual Rolls Equal Channel Extrusion) was developed, which uses the principle of severe plastic deformation for refining of structure. This device is unique in Europe, since the process of structure refining in flat blanks is ate present still under development. The paper analyses the influence of number of passes through the DRECE machinery on the achieved mechanical and forming parameters in low carbon steel. Severe plastic deformation realized in this manner brings substantial refinement of structure. The heat treatment of part of sheet was applied after DRECE processing. Preliminary metallographic analysis was performed for indicative information, so as to find whether grains were really refined. Mechanical properties of studied samples were tested by Vickers hardness method. The paper describes also the methodology of non-destructive residual stresses measurement technique in carbon steel after extrusion of DRECE.
