Abstract: 
Recently, bulk nano-structured materials produced by severe plastic deformation (SPD) have attracted scientists attention. Materials produced by SPD are of great importance because of (1) non-porous structure, (2) great mechanical properties such as high strength and toughness and (3) proper dimension for mechanical and physical testing. Several methods have been introduced for imposing the severe plastic deformation on the metals. In this research, pressing in corrugation dies is carried out on the sheets of low carbon steel at room temperature. The potential of this method in grain refinement and mechanical properties improvement of low carbon steel sheets is investigated using XRD, tensile and hardness tests. The results show that in strain magnitude of 4.64, a microstructure with a grain size of 230 nm is achieved.
