摘　　要：阻尼合金不仅拥有将机械振动能转化为热能并耗散掉的物理特性,而且具有较好的力学性能。如果将阻尼合金制造成零件应用到装备中将能有效控制设备运行时产生的振动和噪声,因此具有重要的工程价值。概述了复相型、位错型、孪晶型、铁磁型和Fe-Mn基阻尼合金的阻尼机制,归纳了影响上述合金阻尼性能的因素以及提高合金阻尼性能的途径。同时,对比了上述各类阻尼合金的综合性能,并对阻尼合金的发展趋势进行了展望。The damping alloys not only have the physical property of converting mechanical vibration energy into heat energy and dissipating it, but also have good mechanical property. If the damping alloys are manufactured into mechanical parts and applied to the equipment, they can effectively control the vibration and noise generated during the operation of equipment, so they have significant engineering application value. The damping mechanisms of multiphase type, dislocation type, twin-boundary type, ferromagnetic type and Fe-Mn based damping alloys were summarized, and the factors that affect the damping capacity of the above alloys and ways to improve that capacity were summed up. At the same time, the comprehensive performance of the above-mentioned damping alloys was compared, and the development trend of damping alloys was prospected.
