“…Technological methods that modify the surface layer of metal reduce the grain size when it is in at least one direction that is less than 100 nm (the process of forming the nanostructure), which is significantly smaller than the base material. Surface layers with nanocrystalline structures have unique physical, mechanical, and chemical properties that improve the performance of parts [9,11,27,29,30].…”

Thermo-deformation treatment refers to methods of strengthening during which strengthened layers with a nanocrystalline structure are formed in the surface layers by modifying the metal surface layer, which changes its phase and structural and chemical compositions, reduces grain size, and improves performance. Grinding of the metal structure was achieved by combining two methods simultaneously during this treatment: the action of a highly concentrated energy source on the surface layer and intense plastic deformation. The source of highly concentrated energy was generated in the contact zone of the tool-disc, which rotates at high speed during friction on the treated surface. Intense deformation was achieved due to the grooves on the tool’s working surface. Dynamic analysis of the thermo-deformation treatment process of flat surfaces of machine parts and a calculation scheme of the surface grinder machine’s elastic system, which is the three-mass model, were developed. When the groove width increased from 4 mm to 8 mm, the force amplitude in the contact zone increased from 10 N to 75 N. Accordingly, the thickness of the nanocrystalline layer increased from 190–220 μm to 250–260 μm, and its hardness increased from 9.3 GPa to 11.1 GPa.

“…Nevertheless, they all have a limb or optical ruler that can be used to determine tool movement, which served as this choice's main idea. The normal component of the force that occurs during processing has been pre-determined by experimental studies [29].…”

This study addresses the evolving challenges in infrastructure development by exploring recent advancements in civil engineering materials. The problem lies in the limitations of traditional materials such as concrete and steel, which, while foundational, may not fully meet the demands of modern construction in terms of sustainability, durability, and resilience. The objective of this review is to assess the role and impact of both traditional and emerging materials, including supplementary cementitious materials, nanotechnology-based materials, and novel reinforcement options, on the performance and sustainability of infrastructure. The scope of the study includes an analysis of the performance characteristics, applications, and limitations of these materials. It also covers the integration of recycled materials, geopolymer-based composites, and biomimetic materials as viable, sustainable alternatives. The review further highlights the significance of functional materials for enhanced performance and energy efficiency and examines advancements in materials testing and evaluation techniques. The methodology involves a comprehensive literature review, synthesizing findings from recent studies to identify key trends, challenges, and research gaps in the field. Results indicate that these advanced materials contribute significantly to improving the sustainability, durability, and resilience of construction projects. However, the study also identifies existing research gaps, particularly in the long-term performance and large-scale application of these materials. The conclusion emphasizes the potential of these innovations to transform civil engineering by creating more robust, sustainable, and efficient infrastructure. Recommendations include continued research and development efforts to address identified knowledge gaps, fostering innovation, and adapting to the rapidly changing demands of the built environment.
