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Kf和DFR值进行了计算,并研究了其随腐蚀年限变化的规律。
Accelerating corrosion test and fatigue test were done to LY12CZ specimens successively. And then with test results, fatigue notch factors K f and DFR of specimens under different corrosion years were calculated, and their changing law were studied.
