摘要
研究了Al2O3／Al复合材料的室温和高温阻尼行为，发现增强物含量增加，此复合材料的阻尼性能显著增加，优于铝合金。较多的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 behavior of Al2O3/Al composite both at room temperature and hightemperature was studied in this paper and it was found that damping of the compositeincreased with inerease of volume fraction of Al2O3 particles. The dislocation damping andthe interface damping were the main contributors to damping mechanism of composite.
