Abstract
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.
Highlights
In piping systems of power plants, T-shaped tubes are used to connect heat pipes [1,2,3,4]. Their operating conditions determine the requirements for materials and their properties for the manufacture of these T-tubes
They are mainly made from resistant non-ferrous alloys that resist treatment [5,6,7,8,9]
An important value here is the rate of deformation [11,12,13,14], which affects the intensity of the deformation
