Study of the acoustic properties of new smelted steels alloyed with chromium, vanadium, and manganese

Abstract

The article presents the results of a comprehensive study of the acoustic, damping, and vibration properties of newly cast steels alloyed with vanadium, chromium, and manganese. The relevance of the work is determined by the growing industrial need to reduce impact noise and vibration generated during the operation of machinery, mining, and metallurgical equipment. Increased acoustic loads lead to accelerated wear of components, reduced reliability of units, and adverse effects on workers, which makes the search for new materials particularly important. The study includes an analysis of literature data on existing noise-reduction methods and demonstrates the advantages of using alloys with enhanced internal damping compared to traditional structural materials. The experimental part was carried out by modeling impact processes using specialized measuring equipment that made it possible to record sound pressure levels, frequency spectra, and vibration decay rates. Special attention was paid to the influence of chemical composition, phase structure, and grain morphology on the acoustic characteristics of the steels. It was established that the optimal combination of alloying elements promotes the formation of a structure that provides more efficient vibration attenuation. The results obtained can be used in the development of new materials and protective components aimed at reducing industrial noise and increasing equipment durability.
