Fatigue behavior of AW7075 aluminum alloy in ultra-high cycle fatigue region
Original language description
Advanced electron microscopy methods were used with the aim to explain the differences in the response of strengthened AW 7075 T6511 aluminum alloy to fatigue loading at 5 Hz and 20 kHz. The shift of the S-N curve to higher number of cycles to fracture for the specimens tested at high frequency was experimentally determined. This effect is not connected with a change of the fatigue crack initiation mechanism and site from the surface to material interior. The absence of slip markings and cracking of primary intermetallic particles on the surface of cycled specimens were characteristic features. A difference in the dislocation density and dislocation arrangement in the vicinity of the fatigue crack initiation sites was shown to be the only observable effect. However, consistent with the strengthened structure of the alloy, no specific dislocation structure due to the cyclic loading was observed, regardless of the loading frequency and stress amplitude.
