During recent years, deformation technologies based on the severe plastic deformation (SPD) developed extensively. SPD methods are effective for refining microstructures of different materials, which lead to a significant improvement in strength properties. In this case, the researchers had the important task of improving the quality of workpieces with minimal material and energy costs. During a deformation process, carried out with the aim of structure refinement, large macroscopic deformation has a great influence. Currently, we are actively developing innovative ways of forging based on large macroscopic deformation, which can intensify the strain imposed into inner layers of an ingot. The work is aimed at solving the problem of improving quality of preforms produced by fullering with the implementation of severe plastic deformation. Carry out computer simulation of fullering technology and studied stress-strain state metal by deformation.Keywords: Fullering technology, Computer simulation, Stress-strain state, Severe plastic deformation
