Effect of aging treatment on fatigue crack growth in eutectic Sn–Pb alloy

The current work investigated the influence of aging treatment on fatigue crack growth behavior of eutectic Sn–Pb alloy. After aging treatment, the eutectic grain structure changed to particle structure. This seriously influenced the time-dependent fatigue crack growth behavior, as well as the cyclic dependent behavior resistance in near-threshold regime at high frequency, while having slight influence on the crack propagation in Paris regime.
