采用光学显微镜、动态力学分析仪等研究了Sb含量对铸态Mg-8 Zn-4A 1 -0.3Mn镁合金阻尼性能的影响。结果表明，添加Sb后，Mg-8 Zn-4A 1 - 0.3Mn镁合金在低温（<80 °C）下的阻尼性能降低，但其阻尼能力在较高温度（>80 °C）下得到改善。在不同温度下，改性和未改性合金均存在一个阻尼峰，锑的加入推迟了阻尼峰的出现温度。随着锑含量的增加，合金的阻尼性能逐渐降低。在本工作中，最好的阻尼能力，从改性合金中获得0.1wt.%高温下的锑。
The effects of antimony content on damping capacity of as cast Mg–8Zn–4A1–0.3Mn magnesium alloy were investigated by using optical microscopy and dynamic mechanical analyzer, etc. The results indicated that the damping capacity of Mg–8Zn–4A1–0.3Mn magnesium alloy was reduced at the low temperatures (<80 °C) after adding antimony, but its damping capacity was improved at the higher temperatures (>80 °C). There exists a damping peak in both modified and unmodified alloys with different temperature, adding antimony postpones the emergence temperature of damping peak. The damping capacities of the modified alloys were decreased gradually with the increase of antimony content. In the present work, the best damping capacity was obtained from the modified alloy containing 0.1 wt.% antimony at the high temperatures.
