The paper contains the description of technique and the graphs for determination of the optimal curvature radius in the tool for isothermal forging with direct extrusion in axisymmetric matrix. This method is based on solving of the problem of minimizing of plastic deformation total power in flow of metal in axisymmetric matrix without curves, i.e. with free flow of material at the transition. Theoretical solution to the problem was verified experimentally.
