摘　　要：采用内耗检测技术研究了Ti对Fe-14 Mn、Fe-17 Mn和Fe-23 Mn合金阻尼性能的影响,研究了Ti对Fe-Mn系合金相组成和耐蚀性能的影响。结果表明,Fe-17 Mn比Fe-14 Mn和Fe-23 Mn具有更高的阻尼性能;在Fe-Mn合金中加入质量分数为1.0%的钛,合金的阻尼性能均受到影响,合金在固溶处理时,发生了γ-ε转变,转变生成的ε马氏体越多,合金的阻尼性能越好;含钛合金在3%NaCl溶液中的耐蚀性能提高近2倍。The influence of Ti on the damping property of Fe-14Mn, Fe-17Mn and Fe-23Mn % alloys was studied by means of the amplitude-dependent internal friction technique. Also, the effects of Ti on phase constitution and resistance to corrosion were investigated. The results showed that the Fe-17Mn alloy possessed a much higher level of damping property than the Fe-14Mn and Fe-23Mn alloys. The addition of 1.0% Ti slightly affected the damping property of the Fc-Mn alloys. The more the conversion of austenite to martensite, the better the damping property. The corrosion resistance in 3 % NaC1 solution was improved about two times due to Ti addition.
