Abstract
Conditions for ensuring a high damping capacity in high-strength low-cost antifriction materials are determined depending on the content of manganese, methods of fabrication (traditional and powder metallurgy), and type of crystal lattice. The mechanisms of energy dissipation in cast and powder Fe – Mn alloys are studied and the special features of their structure responsible for the elevation of the damping capacity are determined. The possibility of replacement of classical high-damping alloys by Fe – Mn alloys with a hexagonal close-packed lattice is considered.
