中文摘要
为了提高Fe-Mn阻尼合金的抗腐蚀性能，在Fe-Mn二元合金中加入一定量的Cr元素，采用倒扭摆法测试Fe-19Mn，Fe-17Mn-2Cr和Fe-16Mn-6Cr三种合金的阻尼性能，采用失重法测试合金在3％NaCl溶液中的耐腐蚀性能，采用OLYMPUS显微镜分析合金的微观组织。结果表明，在0.5×10-4～5.5×10-4的扭转应变振幅范围内，三种合金的阻尼性能随应变振幅的变化趋势一致，呈现近似线形增加；Fe-19Mn合金阻尼性能高于Fe-17Mn-2Cr和Fe-16Mn-6Cr，而后两种合金阻尼性能相当
英文摘要
In order to improve the corrosive properties of Fe-Mn alloys, Cr was added to the Fe-Mn alloys. The damping properties of Fe-19Mn, Fe-17Mn-2Cr and Fe-16Mn-6Cr alloys were measured using reversal torsion pendulum. The corrosive properties were tested using loss-in-weight method in 3%NaCl solution and the microstructures were observed using OLYMPUS microscope. The result indicated that when torsional strain amplitude changes from 0.5×10-4 to 5.5×10-4, the variation tendency of the three alloys all increases linearly. The damping capacity of Fe-19Mn alloy is better than Fe-17Mn-2Cr and Fe-16Mn-6Cr，both of whose damping capacity are almost the same. The addition of Cr can enhance the corrosive properties of Fe-Mn alloys to some extent.
