“…7c), which suggests the formation of Cr 2 O 3 /Al 2 O 3 /SiO 2 layer that may prevent the further oxidation. This is quite similar to the oxidization of Cr/Al-alloyed damping alloys [33] except the Si addition into MMCr may additionally contribute to the oxidization resistance. The oxidation layer at 900 °C includes a loose outer layer and a dense inner layer (Fig.…”

“…CHEN G [25] also found that the addition of Cr to Fe-17Mn leads to a lower content of ε-martensite, thus affecting the damping property. With the addition of Cr, a large number of dislocations pinned in the alloy decreases the damping capacity at high strain amplitudes.…”

High manganese steel has wide prospects in industry due to their excellent mechanical and damping properties. The quenching structures of high manganese steel are ε-martensite, γ-austenite and α'-martensite. Researches show that the damping properties of high manganese steel are related to these microstructures. Besides, there are many ways to improve the damping property of damping alloys. This paper reviews the damping mechanism and the influences of the addition of alloying elements, heat treatment, pre-deformation and other factors on their damping performance, hoping to provide methods and ideas for the study of damping properties of high manganese steel.

“…In recent years, high damping alloys such as Twin Crystal alloys(Mn-Cu) 1,2 , Ferromagnetic alloys(Fe-Cr, Fe-Al) 3 and FeMn-based damping alloys [4][5][6] have attracted much attention due to their excellent damping properties in construction, ships and industrial equipment. Among many damping alloys, the new Fe-Mn damping alloy has the advantages of excellent mechanical properties, low price and good damping property of high strain amplitude, and has a good application prospect [7][8][9][10] .…”

：In this paper, Fe-20Mn-xNb alloys ware prepared by ball milling and spark plasma sintering techniques. Phase constituents were characterized by X-ray diffractometer and Microstructure were characterized by scanning electron microscopy, and the tensile properties, hardness, compactness and damping properties were tested as well. The results show that after ball milling, the metal powders of Fe-20Mn-3Nb first exhibited an irregular plate-like or flake-like morphology, then large irregular particles were broken into fine particles. The addition of Nb element significantly increases the content of γ and ε phase, promoting the formation of γ and ε, and Fe2(Nb, Mn) phase precipitates in Fe-20Mn-3Nb alloy. And Mechanical properties of the alloy are significantly improved by adding Nb element. The UTS and YS of Fe-20Mn-3Nb alloy are the highest, which are 818MPa and 628.7Mpa respectively, while the elongation of Fe-20Mn-0.5Nb alloy is the highest, which is 31.7% (20.2% higher than that of 0Nb alloy). The hardness and density of the alloy A d v a n c e V i e w can be increased by adding Nb. The fracture mechanism of Fe-20Mn-xNb(x=0.5、 1.5、3) alloys is typical ductile fracture, while the fracture mechanism of Fe-20Mn alloy is quasi-xcleavage fracture. The damping property of Fe-20Mn alloys increases with increasing strain. The addition of Nb can significantly improve the damping properties of Fe-Mn alloys.
