| 中文摘要: |
| 对比分析了3种经典公式计算的不同腐蚀周期下LY12CZ铝合金材料疲劳寿命分散系数Lf， 研究了Lf随腐蚀周期以及应力的变化规律， 并提出了疲劳分散系数的预腐蚀贡献因子的计算公式及与腐蚀影响系数的关系。 |
| 英文摘要: |
| The fatigue scatter factors of LY12CZ aluminum-alloy with different pre-corrosion times were calculated by three kinds of classical equation and analyzed by contrast with each other. The laws of the fatigue scatter factor change with the maximum stress and pre-corrosion times were studied. The calculating equations of pre-corrosion contribution coefficient were established and the relationship between the coefficient and the corrosion fatigue influencing factor was put forward. |
