Abstract
The basic idea of the study is to evaluate the acoustic, vibration, physical-mechanical and damping properties of steels, and to produce steels with nanostructured coatings with enhanced damping properties, providing noise and vibration reduction.The study represented the excitation by mechanical shocks of a steel plate, each with a different level of damping.It has been determined that the sources of vibration damping in metallic-paper, encapsulated (MGB) steels MBG-1, MBG-2, MBG-3 with nanostructure coating in the amplitude-dependent region are elastic twinning, diffusion-free reversible phase transformation and magnetic-elastic energy dissipation.As a result of the studies conducted, new damping metallic materials based on iron have been developed.
