摘要
本文研究0Cr18Ni9Ti丝/铝金属基复合材料拉伸过程和加载—卸载—加载(Felicity效应)测试过程的声发射特性。测试数据表明,类似FRP材料,高计数率事件和Felicity比是评价材料内部损伤的表征参数。
The acoustic emission technique was used to characterize OCr18Ni9Ti/ Al composites during tensile processes and unload / reload cycles (Felicity effect). In metal matrix composites as FRP materials, the high count events and Felicity ratio are the criteria of acceptance / rejection.
