Item Analysis of the Mechanism for the Occurrence of a Functional Response during Plastic Deformation of Metals and Their Alloys(National Metallurgical Academy of Ukraine, Dnipro, 2023) Kuznetsow, E. V.ENG: Purpose. Perfection the method for designing technological operations of metal pressure processing by establishing a functional connection between the parameters of force action and the characteristics of the natural deformation behavior of workpieces during their shape forming process. Methodology. A combined analytical approach, which is based on a synthesis of the results of fundamental and applied research in the field of physics of deformable solids, metal forming technology, as well as in related fields of natural science, is used. Findings. It is shown that the nature of the adaptive functional response of metals and their alloys to deforming influence is determined by the magnitude of possible changes in the thermodynamic potentials of the disturbed volume of the substance. From a technological point of view the most favorable response occurs when the deforming influence on the workpiece is carried out taking into account the natural ability of its substance to relaxation. Originality. The functional relationship between changes in the thermodynamic potentials of the volume of a metal or alloy and its adaptive behavior during the deformation process, as well as in the postoperative period, is described. Practical value. The findings make it possible to optimize the technological processes of machining of metals and their alloys by pressure, taking into account the natural properties and behavioral characteristics of each concrete material under concrete production conditions.
