摘要
通过内耗检测技术研究了氮对Fe-14．1Mn和Fe-16．5Mn合金阻尼性能及对Fe-Mn系合金相组成和抗腐蚀性能的影响。结果表明：Fe-14．1Mn比Fe-16．5Mn合金具有更高的阻尼性能；合金中加入质量分数为0．2%的氮,两种合金的阻尼性能略有改变,合金在固溶处理时,发生了γ-ε转变,转变生成的马氏体越多,合金的阻尼性能越好；并且含氮合金在1mol/L硫酸水溶液中的抗腐蚀性能提高2倍。
The influence of nitrogen on the damping capacity of Fe-14.1Mn and Fe-16.5Mn alloys was studied using amplitude-dependent internal friction technique. The effect of nitrogen on phase constitution, mechanical properties and corrosion resistance was investigated. The Fe-14.1Mn alloy possessed a much higher level of damping capacity than the Fe-16.5Mn alloy. The addition of approximately 0.2 wt.% of nitrogen slightly affected the damping capacity of the Fe-14.1Mn alloy and increased the damping capacity in the Fe-16.5Mn alloy. The more austenite converted to martensite, the better damping capacity was obtained after heat treatment. The corrosion resistance of both alloys in 1mol/L sulphuric acid solution was improved by more than two times due to nitrogen alloying.
