Abstract Various methods have been proposed to produce metallic and bulk form materials.Severe plastic deformation, the ways in which you can set quite a lot of mechanical work applied to the metal. Various methods have been proposed to produce metallic and bulk form materials. However, despite the widespread need for tubes with high strength to weight ratio, few studies and attempts have been done to produce ultra-fine and nano structures.Ultra-fine grain metal created by the process have a high resistance by itself. therefore, these can be as high strength steels are used in harmony with the environment. In this study, optimal design of a cast is done in order to increase the homogeneity of the material microstructure and reduce applied force of the pipe production process.Finite element software is used to design the desired format. Since the framework has been designed based on the pressure in angular channels with parallel tube, the channels angles, corners and curved angles, reshaping and the channel radius ratio, the coefficient of friction between the pipe and the channel and the number of passes are the parameters affecting the process.The effect of the above parameters in a homogeneous effective strain rate and force of the process has been studied.
