Abstract

New production technologies have been developed over these last few years as answers in response to new market needs, such as higher production flexibility, lower volume batches, more complex shapes for final pieces and new materials. Cold roll-beating is an advanced precision plastic forming technology to better meet the current requirements. To investigate a material’s behavior in cold roll-beating forming operations, in this paper the principal of slab cold roll-beating was briefly introduced and slab cold roll-beating experiments were carried out, and results of the analysis conducted on the produced pieces in terms of metallographic structure and hardness distributions were reported. Our results show that the cold roll-beating forming can cause the metal surface to harden while improving the mechanical properties of the material, which is interesting in order to understand a material’s behavior when it is subjected to this peculiar deformation process; furthermore, it is of great guiding significance for further applications of the new forming technology.
