Abstract

The widespread use of aluminum alloys is determined by their technical, physical and mechanical properties. The purpose of this paper is to present the characteristics of thermomechanical models of aluminum alloys hot deformation and to explain how they impact the properties of the these alloys. The application of the workpiece rolling process under the conditions of isothermal deformation makes it possible to maximize the effect of ductility. The deformation of hot workpieces is done by the tool heated to the same temperature (or close to them). Such a scheme of hot deformation will reduce the effort by increasing the ductility of the treated metal which occurs due to the full course of stabilizing processes. Uniform deformation of the workpiece provides a good and comprehensive reconstruction of the structure, in the absence of complicated deformation zones and local overheating. And, as a result, it reduces the dispersion of properties in the workpiece volume. It was established that workpieces rolling in conditions of isothermal deformation are reduced the of metal pressure on a roll in 1.8 times or even more.
