Abstract

This paper studies the behavior of non-alloy sheet steel in very low plastic deformation. The steel was subjected to temper rolling (skin pass) with different ratios till 5%. The sheet steel also was subjected to aging after temper rolling. The tensile curves were plotted and their characteristics were determined. The work-hardening coefficient (n) was determined after temper rolling directly and after aging to judge the general behavior of sheets. The microstructure observation was carried out o notice the surface stretcher strains (kinks). Lüder’s bands were observed in aged steel sheets leading to high surface roughness. The surface roughness was measured after temper rolling or aging to judge the surface quality.
