In modern science and industry, there is a growing need for materials with enhanced properties, particularly strength. However, many high-performance materials, such as certain types of metals, alloys, and polymers, do not undergo traditional hardening, which limits their application in areas where high mechanical properties are critically important. This research is focused on developing new methods for strengthening the surface layers of such materials. We expect that the results of this study will significantly expand the possibilities for using these materials, especially in fields such as aerospace and medicine, ensuring greater durability and reliability of products. This scientific article explores the influence of deformation cutting on the microhardness and deformation strengthening of the surface layer of titanium alloys VT8 and VT1-0. The research aimed to determine the effectiveness of deformation cutting as a method for strengthening the surface layer of titanium alloys with different thermal conductivity. The novelty lies in studying the impact of deformation cutting on the microhardness and deformation strengthening of these alloys, comparing the effectiveness for alloys with different thermal conductivity, as well as establishing limitations and directions for further research. The results showed that deformation cutting leads to an increase in microhardness by 10–15% for VT8 and by 40% for VT1-0, explained by the difference in thermal conductivity of the alloys. For alloys with low thermal conductivity, such as VT8, additional sources of deformation or temperature influence are necessary to achieve greater strengthening. The practical significance lies in utilizing the research results to develop new technologies for strengthening the surface layer of titanium alloys with different properties. Thanks to this approach, the possibilities for strengthening materials will significantly expand, paving the way for the creation of new generations of strong and lightweight structures. Implementing these innovative methods may contribute to a revolution in manufacturing, reducing production costs and improving the environmental sustainability of processes.
