Abstract: Iron-based damping alloy, which converts part of vibration energy into heat energy by its own mechanism, can weaken the impact of vibration and noise on equipment and workers effectively, and it has characteristics of superb processability, excellent corrosion resistance, wide operating temperature range and low price. However, the rational matching of damping and mechanical properties of iron-based damping alloy is still a difficult problem that has not been effectively solved and cannot meet the practical engineering application. Heat treatment, element doping and other methods were carried out to optimize the damping performance or mechanical properties of iron-based damping alloys, but almost all of them deteriorated the damping performance when improving the mechanical properties. In order to provide a suggestion for exploring effective process methods to control damping and mechanical properties, the damping mechanism, influencing factors of damping performance and mechanical properties of iron-based damping alloys are analyzed. Finally, the research directions of iron-based damping alloys are prospected.
