Slow hot deformation makes it possible to achieve a significant growth of deformation without the destruction of the material and avoiding a significant decrease in pressure when forming difficult-to-deform non-ferrous alloys. This is especially important when it is necessary to obtain products that operate in severe conditions, for example, in propulsion systems. The article discusses the manufacture of hollow T-shaped connectors by means of forming, namely, by means of extrusion in orthogonal planes and piercing. It was assumed that these operations took place under isothermal conditions. Expressions for calculating the force values of the processes are obtained. Using these expressions, the influence of the degrees of deformation on the forces of extrusion and piercing was investigated.
