Metallic damping materials, a kind of materials which take great importance to reduce vibration and noise, can be both used in structural and functional applications, mainly including damping alloy, damping metal matrix composite and metal foam. In the present paper the damping mechanisms of metallic damping materials are introduced firstly. Secondly, the problems that exist in current metallic damping materials and progress of the research on them are also discussed. Finally,it's pointed out that exploring new damping mechanism and researching high damping metal matrix composite which exhibits superior comprehensive performance is the direction of future research and development prospect of metallic damping materials.
