The research is aimed at the development of new methods of strengthening metals. This scientific article investigates the effect of pressure treatment on microhardness and strain hardening. The purpose of the study was to determine the effectiveness of the deforming effect as a strengthening method. The novelty is the study of the impact of the deforming effect on the microhardness and strain hardening of these alloys, the comparison of efficiency, as well as the establishment of limitations and directions for further research. The results showed that the deforming effect leads to an increase in microhardness. For a number of alloys, additional sources of deformation are required to achieve a greater degree of strengthening. The practical significance lies in the use of research results for the development of new technologies for strengthening alloys with different properties. Thanks to this approach, the possibilities of strengthening materials are greatly expanded, opening the way for the creation of new strong and light structures. The implementation of these innovative methods can contribute to a revolution in production, reducing production costs and improving the environmental friendliness of processes. The level of mechanical properties of metals and alloys in work is evaluated based on the results of tests using different loading methods. The most complete information about the properties of metals can be obtained by the method of tensile testing. For the theoretical analysis, the energy method was used in the work, which made it possible, using force parameters, mechanical properties of the workpiece and the number of simultaneous deforming effects, to determine their numerical values, which, in turn, allows to find the degree of deformation effect on the metal and the degree of strengthening, which at the same time is obtained The work also obtained a dependence for determining the rotational moment of roll forming of bent profiles.
