摘　　要：分析了减振铸铁、铁锰系合金和铁铬铝系合金的阻尼性能,探讨了这三种典型系列阻尼合金的阻尼机制。结果表明,铁磁性型阻尼合金的阻尼性能显著优于其他阻尼机制的阻尼合金。The damping properties of damping cast,FeMn alloys and FeCrAl alloys were analyzed. The damping mechanism of the three kinds of damping alloys were discussed. The results show that the damping properties of the ferromagnetic type damping alloy is significantly superior to the damping alloys which exhibit other damping mechanisms.
