| Abstract: | First, accelerated corrosion tests were carried out for LY12CZ, then, tension strength tests and fatigue tests were conducted. The equivalent environment spectrum of accelerated corrosion was applied to simulate calendar corrosion environment. The results show that:1) the tension strength of LY12CZ Aluminium does not change in statistics in some calendar years and then descends a little; 2)the fatigue strength is degraded with calendar years. On the basis of test data, the dynamic S-N curve is determined. |
| Keywords: | Calendar life Equivalent environment spectrum Fatigue strength |
