Purpose. Review research of the influence of characteristics parameters of the upsetting process before the operation of drawing on the uneven strain distribution in the forgings from titanium alloys by mathematical modeling. Design/methodology/approach. Decided to use the mathematical modelling of the forging process by using the programm software, that is based on the method of finit elements, “Forge 2008”. Findings. The result of this work - are graphical dependences of deformation non-uniformity. In the analysis of simulation results revealed the positive effect of the upsetting operation before drawing, namely, that with increasing the shape factor of the workpiece and the degree of deformation at upsetting process increases the uniformity of distribution of deformation in volume of the metal. Determined that the optimal parameter of the workpiece is h/D = 2, and the optimal degree of deformation at the upsetting process – 30 %.References
