摘　　要：阻尼材料主要通过内耗把振动能转化为其他形式的能量而减少振动和噪声,这种从材料本身入手来实现减振降噪的方法最为直接和有效。作为一种新兴的结构功能一体化钢铁材料,高锰减振钢依靠其大量的ε马氏体和层错等作为阻尼源而呈现突出的阻尼特性,在力学性能、成本以及适用范围等方面也具有独特的综合优势。结合团队前期取得的研究结果,本文主要对高锰减振钢的国内外研究和发展情况进行综述。首先,对高锰减振钢的微观组织特征进行介绍,分析热与变形诱导条件下奥氏体、ε马氏体和α'马氏体间的相互转变行为;其次,总结了高锰减振钢的力学行为与加工硬化机制以及阻尼性能和机理,对比几种强化机制对于力学性能的影响规律,并阐明了影响高锰减振钢阻尼性能的关键性因素;最后,指出了高锰减振钢研发过程中存在的问题,并对未来的研究进行展望。Vibration and noise are considered as public hazards that can affect the daily life of people.The use of additional sound insulation devices or curing of components by design can reduce certain vibration and noise;however,these methods are greatly limited by weight,cost,and vibration-damping effect.Damping materials primarily convert vibration energy into other forms of energy through internal friction to reduce vibration and noise,which is the most direct and effective way to reduce vibration and noise from the material itself.As a new structurally and functionally integrated ferrous material,low-stackingfault-energy and high-manganese transformation-induced plasticity steel has outstanding damping characteristics based on a large number ofε-martensite and stacking faults as damping sources.It also has unique comprehensive advantages in mechanical properties,cost,and scope of application,indicating its broad application potential.Based on previous research results,this paper primarily summarizes the research and development of high-manganese damping steel at home and abroad.First,the microstructural features of high-manganese damping steel are introduced,and the complex thermal/deformation-induced transformation behavior among austenite,ε-martensite,andα'-martensite is investigated.Second,the mechanical behavior,work-hardening mechanism,damping performance,and the mechanism of highmanganese damping steel are summarized and analyzed.The influence of several strengthening effects on mechanical properties is compared,and the key factors affecting the damping properties of high-manganese damping steel are clarified.Finally,the problems in the research and development of high-manganese damping steel are highlighted,and future research is prospected.
