摘要: 铁基阻尼合金是一种依靠自身机制将部分振动能转化为热能散发掉的减振材料,能够有效减弱振动与噪声对设备和工人的影响,并且拥有加工性好、耐蚀性好、使用温度范围宽以及价格低廉等特性。然而,铁基阻尼合金的阻尼性能与力学性能的合理搭配仍是未有效解决的难题,无法满足实际工程应用。研究者发现热处理、元素掺杂等手段对铁基阻尼合金阻尼性能或力学性能能够产生不同程度的优化,但在提升力学性能时几乎都会使阻尼性能恶化。为了给探究调控阻尼与力学性能有效的工艺方法提供参考,对铁基阻尼合金的阻尼机理、阻尼性能影响因素以及力学性能的特点进行了阐述,最后对铁基阻尼合金研究方向进行了展望。

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.

Key words: iron-based damping alloy, influence factor, mechanical properties
