| 摘 要： | 本文较全面地研究了室温空气、潮湿空气、盐雾、盐雾加二氧化硫、人造海水环境下的ＬＣ４ＣＳ高强铝合金抗疲劳和裂纹扩展行为，揭示了各种环境介质对ＬＣ４ＣＳ高强铝合金的影响。本文将ＤＦＲｃｕｔｏｆｆ这一新概念引入腐蚀疲劳领域，为新老飞机寿命评估提供了重要依据。

| Abstract: | broad experimental study on corrosion fatigue behaviour of LC 4 CS high strength aluminum alloy was carried out.Axial fatigue tests and fatigue crack propagation tests in laboratory air environment,hu-midity air,salt fog,salt fog+SO_2 and artificial sea water environment were performed.Significant envi-ronment effect was found.A new concept of DFRcutoff was introduced to evaluate corrosion fatigue resis-tant which could become other important basis for life evaluation of new and aged aircraft. |
