Paper Title:
The Influence of Water in Fuel Tank Environment on Fatigue Property of Pre-Corroded 7XXX Aluminum Alloy
  Abstract

The fatigue life experiments of the pre-corroded 7XXX aluminum alloy(Kt=1 and Kt=3)were tested in environment of laboratory air and water in fuel tank, the median fatigue life and the safe fatigue life of the reliability of 99.9% and confidence of 95% can be obtained. The fatigue life of the pre-corroded 7XXX aluminum alloy reduced significantly because of the water in fuel tank environment, the fatigue life in the environment with water in fuel tank was 6.253% (Kt=1) of the fatigue life in laboratory air environment under the high stress level, the fatigue life with water in fuel tank environment significantly reduced under the low stress level, it was 1.658%(Kt=1) of the fatigue life in laboratory air environment. The fatigue life in the environment with water in fuel tank in different stress level was reduced almost fairly (Kt=3), it was 20.63% (Kt=3) of the fatigue life in laboratory air environment.
