【 摘 要 】

A cold forming technology (cold drawing) produces precise seamless tubes, which can be found in various industries and applications. A high shape accuracy is achieved while the material is reinforced due to plastic deformation during cold forming. The reinforcement of the material in the forming process largely depends on the degree of deformation and plastic properties of the material. The purpose of this study is to compare results of stereological methods used in metallography with data from FEM simulation obtained using software DEFORM and Lagrangian method. Values of strain obtained experimentally and by FEM simulations are supplemented by results of Vickers hardness measurements and mechanical properties obtained by tensile testing after each cold draw operation.
