摘要

This article presents the impact of continuous plastic deformation SPD with the DRECE technique on a structure and properties of low carbon IF steel. The impact of numbers of passes on a change of mechanical properties of tested steel, such as tensile strength TS and yield strength YS, was tested. Within the SPD techniques an unconventional method of deformation was used, which is DRECE - Dual Rolls Equal Channel Extrusion developed on VSB - Technical University in Ostrava. This technique uses reproducible plastic deformation to refine the structure and improve the mechanical properties of a metal band [1]. Numerous changes in the structure and they were associated to evolution of a dislocation structure and grain refinement were observed. In the case of the tested steel the increase of resistance properties was confirmed after the DRECE process after first pass through the device. The biggest hardening of the material is observed after the fourth pass
