| 阻尼合金通过形成复杂的相结构或者引入微观缺陷来增加材料的内耗，在振动或冲击作用下能够吸收和消耗能量，从而有效降低振动和噪声，在航空航天、汽车制造、精密仪器等领域有广阔的应用前景。随着交通、铁路、信号传输等领域对减振以及传输质量要求的提高，其应用领域越来越广泛，对材料结构功能一体化的需求也越来越高。本文简要论述了复相型阻尼合金、位错型阻尼合金、铁磁型阻尼合金以及孪晶型阻尼合金的阻尼机理，分析对比了国内外不同成分的阻尼合金，总结归纳了阻尼合金的研究现状，通过适当的合金设计和热处理工艺，引入不同的阻尼源，改变合金的成分或相结构，可以显著提升合金的阻尼性能和力学性能。对阻尼合金的发展趋势做出了展望，强调了研制新型复合阻尼机制合金的重要性，材料复合技术通过将不同特性的材料结合起来，有助于提高合金的阻尼峰值，扩大合金的适用范围，同时本文提出了对微观结构与阻尼关系深入研究的必要性，这将对分析孪晶型阻尼合金阻尼机制具有重要的意义。 |

| Damping alloys can effectively reduce vibration and noise by forming complex phase structures or introducing microscopic defects to increase the internal friction of materials, which can absorb and dissipate energy under vibration or shock, so they have broad application prospects in aerospace, automobile manufacturing, precision instruments and other fields. As the requirements for vibration damping and transmission quality in transportation, railroads, signal transmission and other fields increase, the application fields of damping alloys are becoming more and more extensive, and the demand for functional integration of the material structure is also increasing. The damping mechanisms of multi-phase damping alloys, dislocation damping alloys, ferromagnetic damping alloys, and twin-boundary damping alloys were briefly discussed. Damping alloys of different compositions at home and abroad were analyzed and compared. The current research status of damping alloys were summarized. Through the introduction of different damping sources, appropriate alloy design and heat treatment processes can significantly enhance the damping and mechanical properties by changing the composition or phase structure of the alloy. The development trend of damping alloys is expected. The importance of developing new composite damping mechanism alloys is emphasized. The material composite technology helps to increase the damping peak value of alloys and expand the range of alloys by combining materials with different properties. An in-depth study of the relationship between microstructure and damping is important for analyzing the damping mechanism of twin-boundary damping alloys. |
