Investigation on fatigue crack propagation behaviors in the thickness direction of 2519A aluminum alloy thick plate

Influence of plastic deformations on both yield strength and torsional fatigue life of non‐ferrous alloys

“…Such a ratio ranged between 0.30 and 0.53 for Charpy impact value, whereas was equal to 1.19 and 0.43 for fatigue crack‐growth rates relatively to the T‐L and T‐S orientation, respectively. Liu et al 6 examined the influence of microstructures, characterizing a 2519A aluminum alloy thick plate, on the fatigue crack propagation behavior, by considering specimens subjected to fatigue loading in both rolling direction (named RD) and thickness direction (named ND). It was found that the ND specimens were more susceptible to fracture with respect to the RD specimens, with a weak fatigue crack propagation resistance due to the presence of a coarse second phase and with a mainly intergranular crack propagation mode.…”
