Purpose: The goal of the study was to determine the influence of controlled deformation by RCS (repetitive corrugation and straightening) process on the structure and mechanical properties of S235JR steel. The influence of process parameters on the above properties was investigated. Design/methodology/approach: This study was aimed to investigate structure and mechanical properties of hot rolled rods of S235JR steel, subjected to intensive plastic deformation using the RCS (repetitive corrugation and straightening) method. Findings: Microstructure of the examined steel of S235JR grade is typical for hot rolled conditions. It was found out that in the initial material the perlite lamellae grew mainly in the direction perpendicular to the axis of the rod, i.e. in the direction of the highest rate of heat dissipation. The perlite lamellae in the rods after bending presented more random arrangement, and some of them were crushed. The process of bending should, therefore have a positive influence (decrease) on the anisotropy of mechanical (plastic) properties. Practical implications: Investigation results can be easily applied into industrial technology. Originality/value: This paper presents the results of study of the structure and mechanical properties S235JR steel after controlled deformation.
