FCG tests were conducted at an elevated temperature of 950 °C and a stress ratio (<em>R</em>) of 0.1 on specimens with PSP layer thicknesses of 1.5 mm, 2 mm, 3 mm, and 4.5 mm to assess the influence of PSP thickness on fatigue crack growth behavior.

In addition, transmission electron microscopy (TEM) was utilized to observe and analyze the intergranular corrosion and fatigue crack tip morphologies, and then used to propose a damage mechanism model for aluminum alloy under the alternating action of a corrosive environment and fatigue loads. Our results showed that the predominant corrosion damage mode for ZL114A aluminum alloy in the alternating corrosion/fatigue test was intergranular corrosion. The eutectic Si phase at the grain boundaries served as the cathode, while α-Al underwent dissolution as the anode. The fatigue load induced dislocation accumulation at the tip of the intergranular corrosion, causing separation of the interface formed between the matrix and secondary phase. On the other hand, the fatigue load promoted cracking of the grain boundaries after corrosion, which ultimately resulted in the initiation of fatigue cracks. The initiation time for the fatigue cracks during the alternating test had a considerable effect on the fatigue life of the samples. When durations of the corrosion stage (<em>ΔT</em>) and numbers of load cycles during the fatigue testing stage (<em>ΔN</em>) were relatively small (Δ<em>T</em> &lt; 72 h, Δ<em>N</em> &lt; 30,000 cycles), no fatigue cracks were initiated during the alternating process and the final stage fatigue life of the material was comparable to the fatigue life after pre-corrosion for the same corrosion time.
