INFLUENCE OF SPD PROCESS ON LOW-CARBON STEEL MECHANICAL PROPERTIES

Abstract

The paper analyses the influence of different values of the angle of the deformation zone in the forming tool on severe plastic deformation (SPD) process and on mechanical properties of resulting steel strip. Forming equipment using the severe plastic deformation (SPD) process and DRECE (Dual Rolling Equal Channel Extrusion) method built and installed in the laboratory for the development of new technologies at the Faculty of Mechanical Engineering of VSB – the Technical University of Ostrava is described. Tests were carried out at selected low-carbon deep-drawing steel DC01. By the magnetoelastic method, the residual stresses in the material after separate passes were analyzed. DRECE method of forming brings compression stress into the material, which is favorable for further use.
