| 摘 要： | 通过内耗检测技术研究了氮对Fe-14．1Mn和Fe-17．6Mn合金阻尼性能的影响，以及氮对Fe，Mn系合金相组成和力学性能的影响。结果表明，Fe-14．1Mn比Fe-17．6Mn合金具有更高的阻尼性能；合金中分别加入质量分数为0．2％的氮，两种合金的阻尼性能略有改变，同时Fe-17．6Mn合金的σb从465MPa增加到695MPa，δ从3．7％增加到12．6％，而Fe-14．1Mn合金的σh从470MPa增加到690MPa，δ从5．4％降到4．0％。

| Abstract: | The influence of nitrogen on the damping capacity of Fe-14. 1Mn and Fe-17.6Mn alloys was studied by means of amplitude-dependent internal friction technique, and the influence of nitrogen on phase constitution and mechanical properties was also investigated. The results show that Fe-14. 1Mn alloy possesses higher level of damping capacity than that of Fe-17.6Mn alloy. The addition of approximately 0.2% nitrogen slightly affects the damping capacity of Fe- 14. 1Mn alloy and increases it of Fe-17.6Mn alloy. At the same time,the ultimate tensile strength of Fe-17.6Mn alloy increases from 465 to 695 MPa, and the uniform elongation increases from 3.7% to 12. 6%. The uhimate tensile strength of Fe-14. 1Mn alloy increases from 470 to 690 MPa,while the uniform elongation slightly decreases from 5.4% to 4.0%. |
