研究了Fe Mn基减振合金的减振机制 ,并深入分析了固溶处理对Fe 14 0 4Mn 0 2 2C减振合金阻尼性能的影响。研究结果表明 ,该合金经固溶处理后 ,发生了γ→ε转变 ,固溶处理温度越高 ,γ→ε转变生成的马氏体越多 ,合金的阻尼性能随固溶处理温度的升高而提高 ,在 10 0 0℃时 ,合金的阻尼性能达到最大值 ,随温度的进一步升高 ,阻尼性能反而恶化。

The damping mechanism of Fe-Mn base alloys was studied and the relationship between the damping mechanism and solution treatment temperature was clarified too in this article.The results show that after solution treatment,the transformation of γ phase to ε phase has occurred in Fe-14.04Mn-0.22C alloy,and the higher the solution temperature,the more the martensite.The damping capacity of Fe-14.04Mn-0.22C alloy improves as the increase of solution temperature,and reaches the maximum value at about 1000℃.As further increase of the temperature,however,the damping capacity degrades.
