Abstract To determine the system of metal forming of uranium in order to produce sheets, bars, tubes, etc., an investigation was made of the force and deformatión characteristics in rolling, extruding, wire-drawing, and stamping of uranium. Determinations were made of the relationship between releability of uranium and the temperature and between the average specific pressure of uranium on the rolls, the absolute widening and the degree of reduction (from 10 to 50%), and the temperature (from 400 to 1000 °C). A calculation of the average specific pressure of uranium on the rolls according to the analytical formula of A. I. Tselikov [1] showed good agreement between the calculated data and the experimental results. A study was made of the dependence of the extrusion stress on the drawing (up to 54), the temperature (from 250 to 800 °C), and the scale factor (the ratio of diameters of the containers equal to 5). The concepts are introduced of extrudability and the modulus of the extrusion stress, methods are proposed for calculating them, and the dependence is determined on the temperature of extrudability and the modulus. A study is made of the dependence of the wire drawing stress and the safety coefficient on the degree of deformation (from 5.5 to 34%).
