In the present research, effects of (1) alloying elements of Cr, Mn, Co and N, (2) thermomechanical treatments and (3) microstructure and phases of a (bcc, inducing α^1 phase (bct)), γ and ε on the damping property of Fe-5〜12%Cr-6〜30%Mn-0〜4%Co alloys have been investigated and the present investigators have develped a new Fe-Cr-Mn-Co alloy with high strength and high damping property. Brief summaries are made as followings,(1) The highest damping property has been obtained on the Fe-12%Cr-22%Mn alloy which are cold rolled by 15 to 50% after the solution treatment at 1373K for 1hr. ε phase has a significant effect for increasing the damping property of Fe-12%Cr-22%Mn alloy, whicle α , α^1 and γ phases have no effect on the damping property of the alloy.(2) The addition of 4%Co is very effective to give the high damping property to the Fe-12%Cr-22%Mn alloy.(3) Cold rolling temperature and subzero treatment are alos important factor t for increasing damping property of Fe-Cr-Mn-Co alloys. Fe-12%Cr-22%Mn-4%Co alloy winch is 50% cold rolled at 360K and subzero treated at 223K has the highest damping property.

本文研究了(1)铬、锰、钴、氮的合金化元素、(2)形变热处理和(3)体心立方诱发α^1相(Bct)、γ和ε对Fe-5~12%Cr-6~30%Mn-0~4%Co合金减振性能的影响，开发了一种新型的高强高阻Fe-Cr-Mn-Co合金。简要总结如下：(1)冷轧15%~50%的Fe-12%Cr-22%Mn合金经1373K固溶处理1hr后，具有最高的减振性能。ε相对提高Fe-12%Cr-22%Mn合金的减振性能有显著作用，而α，α^1和γ相对合金的减振性能影响不大.(2)添加4%Co对提高Fe-12%Cr-22%Mn合金的减振性能非常有效.(3)冷轧温度和深冷处理也是提高Fe-Cr-Mn-Co合金减振性能的重要因素.Fe-12%Cr-22%Mn-4%Co合金绞盘在360K冷轧50%，223K深冷处理具有最高的减振性能。
