腐蚀环境下材料的疲劳缺口系数

Fatigue Notch Factor of Corrosion Material

摘要:

采用当量加速环境谱对LY12CZ铝合金材料进行了不同年限的加速腐蚀试验,并对腐蚀后的试件进行疲劳试验,根据试验数据,对不同腐蚀年限下试件的疲劳缺口系数和DFR值进行了计算,并研究了其随腐蚀年限变化的规律。

Abstract:

Accelerating corrosion test and fatigue test were done to LY12CZ specimens successively. And then with test results, fatigue notch factors and DFR of specimens under different corrosion years were calculated, and their changing law were studied.
