摘要
研究了ＳｉＣｐ／ＬＹ１２铝基复合材料及其基体铝合金的阻尼行为，发现随温度升高，铝基复合材料的阻尼性能显著增加，优于铝合金。并且增强物含量越多，复合材料的阻尼性能越好。研究认为位错阻尼和界面阻尼是提高复合材料阻尼性能的原因。
The damping capacity of SiCp/LY12 composite was high at elevated temperature and was better than that of Al alloyWith increasing of volume fraction of SiC particles in the composite,its damping capacity was increased graduallyBoth of dislocation damping and interface damping were the main contributors to damping mechanism in the composite
