| 摘 要： | 通过内耗检测技术研究了氮对Fe-14.1Mn和Fe-16.5Mn合金阻尼性能的影响.并深入研究了氮对Fe-Mn系合金抗腐蚀性能和相组成的影响.研究结果表明: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,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;并且含氮合金对1 mol/L硫酸水溶液的抗腐蚀性能提高约2倍.

| Abstract: | The influence of nitrogen content(mass fraction,%)on the damping capacity of Fe-14.1Mn and Fe-16.5Mn alloys was studied by using the amplitude-dependent internal friction technique.Also,the effect of nitrogen on phase constitution and resistance to immersion corrosion was investigated.It was found that the Fe-14.1Mn alloy possesses a much higher level of damping capacity than the Fe-16.5Mn alloy.The addition of approximately 0.2%(mass fraction) of nitrogen slightly affects the damping capacity of the Fe-14.1Mn alloy and increases it in the Fe-16.5Mn alloy.The more austenite is converted to martensite,the better damping capacity there is for heat treatment.The corrosion resistance in 1 mol/L sulphuric acid solution is improved by more than twice in both alloys due to nitrogen alloying. |
