Fe–Mn martensitic alloys for control of noise and vibration in engineering applications

Conventional methods for reducing vibration in engineering designs may be undesirable or inadequate in conditions where size or weight must be minimized or where complex vibration spectra exist. Alloys which combine high-damping capacity with good mechanical properties can provide attractive technic...

Description
Summary:Conventional methods for reducing vibration in engineering designs may be undesirable or inadequate in conditions where size or weight must be minimized or where complex vibration spectra exist. Alloys which combine high-damping capacity with good mechanical properties can provide attractive technical and economic solutions to problems involving seismic, shock and vibration isolation. To meet these trends, we have developed a new high-damping Fe–17% Mn alloys. Also, the alloy has advantages of good mechanical properties and more economical than any other known damping alloys (one-quater of the cost of non-ferrous damping alloy). Thus, the high-damping Fe–17% Mn alloy can be widely applied to household appliances, automobiles, industrial facilities and power plant components with its excellent damping capacity (SDC, 30%) and mechanical property (UTS 700 MPa). It is the purpose of this paper to introduce the characterization of the high-damping Fe–17% Mn alloy and the results of retrofit several such applications.
