In this research, we developed Fe-12 mass% Cr-22 mass% Mn alloy with high damping property and high strength. Material's damping property and it’s addition elements have been investigated. Particularly, the effects of the phases of alpha, gamma and epsilon martensite, which constitute the structure of the alloy Fe-12 mass% Cr-22 mass% Mn alloys, on the damping capacity at room temperature has been investigated. Various fractions of these phases were formed depending on the Co and Si contents and cold work degree. It was found that the combination of 22 mass% Mn 4% Co-0.4% Si and 50% cold rolling formed the largest volume fraction of epsilon martensite phase and showed the highest damping capacity. The other phases of alpha and gamma had actually no effect on the damping capacity. It was also found that 50% clod worked Fe-12% Cr-22% Mn 4%Co-0.4%Si alloy indicated the largest vickers hardness., Article, 先進ファイバー工学研究教育拠点研究成果報告書 11: 124-125(2005)}, title = {15-5-21 : 繊維機械用Fe-Cr-Mn系制振合金の減衰能特性に及ぼす微細組織の影響}, year = {2005} }
