| Résumé | Under a tension-compression loading condition applied with the frequency of 10Hz and stress ratio of 0.1, the fatigue behavior of the notched aluminum 7050-T7452 coupons was studied using scanning electron microscope (SEM), and SEM-based automated electron back-scatter diffraction (EBSD) that generates images of orientation of grains. The grain micro structure was determined with optical microscope (OM) by employing the lineal intercept method. OM observation demonstrates that the alloy is having a deformation band-based microstructure. The fatigue crack nucleates at grains with high angle (>15 degrees) misorientation in the area characterized by a weak texture and propagates transgranularly. |
