Computer Simulation of Continuous SPD Process Commercially Pure Titanium Using Virtual Full Factorial Experiment with the Influence of Friction Factors

摘要

With the use of computer modeling in the environment of the software DEFORM-3D virtual conducted a full factorial experiment process, equal channel angular pressing (ECAP) by method "Conform" of commercially pure titanium, which evaluated the effect of independent parameters (speed of rotation of the impeller, the friction factor on the side surfaces of the impeller and the factor of friction between the billet and the matrix). As a result of the experiment obtained the regression equation and identified the most important individual factors and their mutual combinations that affect the response parameter are the deformation forces.
