摘要：

The ability to absorb energy of mechanical vibrations by different cellular metallic materials with porosities from 14 to 96% (metallic foams, metallic sponges and sintered metals) is discussed. Different mechanisms of internal losses (thermoelastic and microeddy currents, magnetic domains, dislocations, microcracks) are considered in respect of low weight, peculiarities of structure and applicability for damping of mechanical vibrations.
