dc.description.abstractThe DRECE method belongs to the severe plastic deformation (SPD) processes used for the refinement of sheet metal elements. A forming device used in this method is currently being installed in the workplace in the Centre of Advanced Innovation Technologies, VSB Technical University of Ostrava. In the present work the structural characteristics and fracture morphology of Ck55 carbon steel after the application of the DRECE method with a forming tool angle of 118 degrees are presented. The microstructure results are linked to selected mechanical properties. The tensile, hardness, and fatigue tests are performed. The methodology of non-destructive residual stresses measurement in the carbon steel after the extrusion and application of tensile tests on small samples are important for their use in technical practice. The paper presents the original results of selected properties after the application of the DRECE method on Ck55 steel, which will be used in the future to assess the application of the DRECE method and to determine other directions of the processing of ferrous alloys and steels.cs
dc.description.abstract-enDRECE metod pripada procesima intenzivne plastične deformacije (SPD) koji se koriste za preradu elemenata od lima. Uređaj za oblikovanje koji se u ovoj metodi koristi se trenutno instalira u Centru za napredne inovativne tehnologije, VSB Tehnički univerzitet u Ostravi. U ovom radu predstavljene su strukturne karakteristike i morfologija loma Ck55 ugljičnog čelika posle primene DRECE metoda sa uređajem za oblikovanje od 118°. Rezultati mikrostrukturnih analiza su u vezi sa odabranim mehaničkim osobinama. Izvršeni su testovi istezanja, tvrdoće, i zamora materijala. Metodologija nerazarajućeg merenja zaostalih naprezanja u ugljičnom čeliku posle istiskivanja kao i primena testova na istezanje na malim uzorcima su važni zbog njihove primene u tehničkoj praksi. U ovom radu su predstavljeni originalni rezultati odabranih osobina posle primene DRECE metode na Ck55 čelik, a koji će biti u budućnosti korišćeni za procenu primene DRECE metode kao i za određivanje pravaca rešenja koji se tiču ovog i drugih odabranih vrsta čelika.cs
