| Abstract: |
| Fatigue fracture surface of AA LY12CZ with corrosion damage was studied using scanning electron microscope and energy spectrum analysis. The effect of fatigue fracture feature, alloy element Si and Mg, and the corrosion damage on the fracture process was analyzed. The results indicated that the fatigue fracture surface is tough fracture with multiple fatigue sources; pits introduced by corrosion damage weaken the material property, which serve as crack nucleation sites; proper hardening constituent element introduced during alloying process such as Si and Mg, will make strength and plasticity match, thus improve fatigue performance of materials. |
