Increasing the mechanical properties of DC01 steel by the DRECE method of severe plastic deformation

Abstract

The article is focused on the process of severe plastic deformation (SPD). New method using the SPD principle (DRECE) is described in the article. New method using the severe plastic deformation (DRECE) is particularly suitable for forming metal materials. Materials produced by this technology are characterized by increasing mechanical properties while maintaining sufficient ductility of the materials. In the practical part of the work, experiments were carried out on DC01 steel using the DRECE method. Sheet metal strips were formed through one to seven passes by DRECE method. The thickness of the formed strips was 2 mm, the strips width was 59 mm and the strips length were 1000 mm. The dimensions of the sheet metal strips were limited only by the design of the forming device using the method severe plastic deformation (DRECE). The experiment was performed on a forming tool with angle in the deformation material zone 108 °. The experiment was demonstrated on all sheet metal strips under the same forming conditions. The aim of the experiments was to verify the influence of the number of passes by the forming device on the achieved mechanical properties of the steel. The final part of the article describes the achieved mechanical properties of the sheet metal strip after forming by the DRECE method.
