Mechanical property features of nanomaterials for engineering means

One of the major challenges in mechanical engineering is reducing component vibrations, which can lead to cyclic loading, malfunctions, breakdowns, and increased noise levels. Nanocrystalline materials combine high strength with damping properties, distinguishing them from conventional materials, where enhanced vibration absorption typically comes at the cost of reduced strength. Research has shown that forming a submicrocrystalline structure in steel increases both the internal friction coefficient and the yield strength by a factor of four. This makes nanomaterials suitable for reinforcing critically loaded components, such as internal combustion engine piston pins operating under impact loads and friction. The use of such structures extends the service life of components, reduces maintenance costs, and supports the development of energy-efficient and long-lasting mechanisms. The findings confirm the feasibility of implementing nanotechnologies in mechanical engineering to improve the reliability and environmental sustainability of equipment.
