The paper deals with the issues concerning stand development and methods of carrying out experimental equal channel angular pressing AD0 aluminum alloy blanks. Research on the effect of equipment heating temperature on the energy-power costs, when pressed, is considered as well. The experimental pressing of blanks of 40 mm length and 5.5 mm square section is performed under the following process parameters: channel intersection angle Ф=120 °, channel crossing radius r=3 mm, equipment temperature θ = 20-200 ° C, pressing speed v= 10 mm/s. The experiments have provided data on the changes in power parameters pressing process. Pressing process characteristics are based on the analysis of force change chart. The blank temperature has a significant effect on the pressing force.
Keywords: equal channel angular pressing, intensive plastic deformation, energy-power costs, temperature.

This paper discusses issues related to the process of creating a mathematical model of equal-channel angular pressing of aluminum alloy billets Al+1.9%Mg and study the effects of friction during the pressing process for energy-power costs and strain state of the workpiece material. Calculations conform channel angular pressing cylindrical workpieces 90 mm and a diameter of 5 mm with the following parameters: the angle of intersection of channels F-90 °, the radius at the intersection of channels r – 0.1 mm, temperature workpiece and tool corresponded t = 20 ° C, pressing speed ʋ-10 mm / s, the coefficient of friction of μ = 0, 0.25, 0.5 and 0.75. Shown to increase the coefficient of friction affects the distribution of strains in the workpiece material and energy-power costs.
Keywords: computer modeling, equal channel angular pressing, severe plastic deformation, energy-power cost-stressed state.
