The paper presents the analysis of the three-dimensional strain state for the cogging process of a forging (type: shaft) of the X6CrNiTi18-10 austenitic steel with the application of the finite element method. The results of the thermal-mechanical simulation of the hot cogging process on flat and shaped anvils, taking under consideration boundary conditions applied in industrial practice, are presented. In the research, a new method of forging, consisting in the introduction of the initial forging of the stock on anvils which have convex work surfaces, and further forging on shaped anvils, was applied. The results of the calculations make it possible to determine effective strain distribution, effective stress, mean stresses and temperature in the volume of a forging. The solution was supplemented by the addition of the model of microstructure development in the course of deformation. The conducted research constitutes the basis for determining the best possible technological process of the initial forging of a cast ingot, and provide the possibility of forecasting the deformations and parameters of the microstructure.
